chore: release v1.5.0 (#67)

* chore: release v1.4.0

* feat: timezone-aware locale formatting

- Add TIMEZONE_TO_REGION map for 50+ timezones worldwide
- Combine app language with timezone region (e.g., en + Europe/Berlin → en-DE)
- Fix times displaying in wrong timezone (treated as UTC instead of local)
- Add parseLocalDateTime() to handle ISO strings without UTC conversion
- Users now get regional formatting (24h time, local date format) regardless of app language
- Swedish user with en-SE locale now gets yyyy-mm-dd format and 24h time
- German user with en-DE locale gets dd.mm.yyyy format and 24h time
- Add missing i18n translation key 'lastSent'
- Update all getSystemLocale() calls to pass app language parameter

* chore: release v1.5.0

* fix: timezone-independent test for CI (use 14:00 instead of 22:00)

* fix: make timezone test independent of server timezone

 # MedAssist-ng - AI Coding Instructions
 
+## General Rules
+
+- **English is the primary language**: All code, comments, documentation, commit messages, PR descriptions, and GitHub releases MUST be written in English. The user may communicate in German, but all project artifacts must be in English.
+- **NEVER release without explicit permission**: Do NOT create tags, releases, or version bumps unless the user explicitly asks for it. Always wait for explicit confirmation before any release action.
+- **NEVER create PRs without explicit permission**: Do NOT create Pull Requests, push branches, or merge code unless the user explicitly asks for it. Always present changes and wait for the user to confirm before any git operations that affect the remote repository.
+- **No temporary files**: Delete temporary scripts/files immediately after use. Do not commit temporary debug scripts, test files, or one-off utilities to the repository.
+- **Clean workspace**: Always clean up after yourself. If you create a file for a specific task, delete it once done.
+

 # Database migrations
 cd backend && npm run migrate
+
+# Run tests
+cd backend && npm test              # Run all tests
+cd backend && npm run test:coverage # Run with coverage report
 ```
 
+## Testing (MANDATORY)
+
+> ⚠️ **IMPORTANT**: Every new feature MUST be covered by tests!
+> Pull Requests without tests for new features will not be accepted.
+
+### Test Framework
+- **Vitest 2.1** with v8 Coverage
+- Tests in `backend/src/test/*.test.ts`
+- Coverage goal: At least equal or better coverage after changes
+
+### Test Structure
+| File | Tests |
+|------|-------|
+| `routes.test.ts` | API endpoints (Auth, Medications, Doses, Settings, Share, Planner) |
+| `services.test.ts` | Scheduler utilities (Timezone, Blisters, Usage calculation) |
+| `db.test.ts` | Database schema and operations |
+
+### Writing Tests
+
+```typescript
+// Backend Test Example (backend/src/test/example.test.ts)
+import { describe, it, expect, beforeAll, afterAll } from 'vitest';
+import { createTestApp, createTestUser } from './routes.test'; // Test-Utilities
+
+describe('Feature Name', () => {
+  let app: FastifyInstance;
+  let authToken: string;
+
+  beforeAll(async () => {
+    app = await createTestApp();
+    const user = await createTestUser(app);
+    authToken = user.token;
+  });
+
+  afterAll(async () => {
+    await app.close();
+  });
+
+  it('should do something specific', async () => {
+    const response = await app.inject({
+      method: 'GET',
+      url: '/endpoint',
+      headers: { Authorization: `Bearer ${authToken}` }
+    });
+    
+    expect(response.statusCode).toBe(200);
+    expect(response.json()).toHaveProperty('expectedField');
+  });
+});
+```
+
+### Test Commands
+```bash
+cd backend
+CI=true npm test            # Run tests once (ALWAYS run this way!)
+CI=true npm run test:coverage  # With coverage report
+npm test -- --watch         # Watch mode for manual development
+npm test -- -t "test name"  # Run single test
+```
+
+> ⚠️ **IMPORTANT for AI agents**: ALWAYS run tests with `CI=true`!
+> Without `CI=true`, Vitest runs in watch mode and waits for input.

+
+### Branch Protection
+
+> ⚠️ **IMPORTANT**: The `main` branch is protected!  
+> Direct pushing to `main` is **not possible** - GitHub will reject the push.  
+> All changes must go through Pull Requests.
+
+- **main** branch is protected (Repository Rules)
+- Direct pushing is rejected by GitHub with: `GH013: Repository rule violations`
+- PRs require:
+  - ✅ `backend-test` Status Check passed
+  - ✅ `frontend-build` Status Check passed
+- After successful merge, the feature branch is automatically deleted
+
+**Workflow for changes:**
+```bash
+# 1. Create feature branch
+git checkout -b feat/my-feature
+
+# 2. Commit and push changes
+git add . && git commit -m "feat: Description"
+git push -u origin feat/my-feature
+
+# 3. Create PR (via GitHub CLI or Web)
+gh pr create --title "My Feature" --body "Description"
+
+# 4. Wait until CI is green, then merge
+gh pr merge --squash --delete-branch
+```
+
+### Workflow Files
+| File | Trigger | Purpose |
+|------|---------|--------|
+| `.github/workflows/test.yml` | Pull Requests | Run tests, block PR on failures |
+| `.github/workflows/docker-build.yml` | Push to main, Tags | Tests + Build and push Docker images |
+
+### Adding New Code - Checklist
+1. ✅ Implement feature
+2. ✅ Write tests for the feature
+3. ✅ Run `npm run test:coverage` locally
+4. ✅ Coverage must not decrease
+5. ✅ Create and push feature branch
+6. ✅ Create Pull Request
+7. ✅ Wait until CI is green
+8. ✅ Merge PR (branch is automatically deleted)
+
+## GitHub Releases
+
+> ⚠️ **IMPORTANT**: All GitHub Releases must be written in **English**!
+
+### Release Workflow (MANDATORY for minor/major releases)
+
+The `main` branch is protected - releases must go through the automated release script.
+
+**Release Process:**
+```bash
+# 1. Run release script (creates PR, waits for CI, merges, creates tag)
+./scripts/release.sh [patch|minor|major]
+
+# 2. GitHub Actions creates a DRAFT release automatically
+# 3. User asks AI to write release notes:
+#    "Write the release notes for vX.Y.Z"
+# 4. AI writes descriptive release notes following the style guide below
+# 5. User publishes the draft release with the written notes
+```
+
+> ⚠️ **MANDATORY for minor and major releases**: The AI assistant MUST write proper descriptive release notes!
+> Do NOT just publish the auto-generated commit list. Follow the process above.
+
+**AI Assistant Release Notes Workflow:**
+1. When user asks to write release notes for a version:
+   - Check commits since previous tag: `git log vPREV..vNEW --oneline`
+   - Read through the changes to understand what was added/fixed
+   - Write release notes following the style guide below
+   - Present the notes to the user for copying to GitHub
+
+### Creating Release Notes
+
+> ⚠️ **MANDATORY**: GitHub Releases MUST contain a written message!
+> Not just auto-generated commit lists, but a brief descriptive text.
+
+**Release title:** Use just `vX.Y.Z` (e.g., `v1.4.1`), NOT "Release vX.Y.Z".
+
+**Keep it informative but concise.** Users want to know what changed and where to find it.
+
+**Required structure of release notes:**
+
+1. **"What's New"** (1-2 sentences): Brief intro explaining the main change
+2. **"New Features" / "Improvements"**: Grouped bullet points with **bold feature names** and descriptions
+3. **"Where to Find It"**: Tell users where they can access the new feature
+4. **Breaking Changes Warning** (if applicable): See below
+
+**Style guidelines:**
+- Use `### Heading` for sections (New Features, Improvements, Security, etc.)
+- Use **bold** for feature names in bullet points
+- Keep descriptions on the same line as the feature name
+- Minimal emoji usage (sparingly, not on every line)
+- Always end with "Where to Find It" section
+
+**DO NOT include:**
+- ❌ Technical implementation details (new columns, endpoints, database changes)
+- ❌ Number of tests added
+- ❌ Internal API changes (unless breaking)
+- ❌ Excessive emoji on every bullet point
+- ❌ .gitignore changes or other developer-only file changes
+- ❌ AI/Copilot instruction updates
+- ❌ CI/CD workflow changes (unless affecting users)
+- ❌ Code refactoring without user-visible changes
+
+**Only include user-relevant changes** - things that affect what users see or experience in the app.
+
+**Example of good release notes:**
+
+```markdown
+## What's New
+
+This release introduces a medication refill tracking feature and improves the mobile user experience.
+
+### New Features
+
+- **Medication Refill**: Track when you refill your medications with a single click. Add full packs or individual pills and view complete refill history.
+- **Automatic Stock Updates**: Stock levels are automatically recalculated after each refill.
+- **Refill History**: Each medication shows a complete history of all refills with timestamps.
+
+### Mobile Improvements
+
+- **Centered Tooltips**: Info tooltips now display centered on screen for better readability.
+- **Touch-friendly**: Tooltips close automatically when scrolling on touch devices.
+
+### Where to Find It
+
+The refill button appears in the medication detail modal and in the edit form for each medication.
+
+**Full Changelog**: https://github.com/DanielVolz/medassist-ng/compare/v1.2.3...v1.3.0
+```
+
+### Breaking Changes Warning (CRITICAL!)
+
+> ⚠️ **MANDATORY**: If an update breaks existing configurations or stored data, it MUST be prominently warned about in the release notes!
+
+**Breaking Changes include:**
+- Database schema changes without automatic migration
+- Removed or renamed ENV variables
+- Changed API endpoints
+- Incompatible `.env` format changes
+- Loss of stored data after update
+
+**Format for Breaking Changes:**
+
+```markdown
+## ⚠️ BREAKING CHANGES - Please read before updating!
+
+**Database migration required**: This update changes the database schema. 
+Existing installations need to:
+1. Create backup of `data/` folder
+2. Stop containers
+3. Perform update
+4. If issues occur: Rollback using backup
+
+**ENV variables changed**: 
+- `OLD_VAR` was renamed to `NEW_VAR`
+- `REMOVED_VAR` is no longer supported
+
+**Medication data**: Intake schedules with only one time entry will be automatically 
+migrated. Please verify all times are correct after update.
+```
+
+**What is NOT a Breaking Change:**
+- ✅ New optional columns with DEFAULT values
+- ✅ New ENV variables (with sensible defaults)
+- ✅ New features that don't affect existing data
+- ✅ Bug fixes that correct behavior
+
+**Rule of thumb**: If a user can simply run `docker compose pull && docker compose up -d` 
+without adjusting anything → Not a Breaking Change.

 - **i18n**: All UI text via `t('key')` function, translations in `frontend/src/i18n/*.json`
 
-## Database Schema Changes
+## Database Schema Changes (IMPORTANT: Backward Compatibility!)
 
-When adding new database columns:
+> ⚠️ **CRITICAL**: The app MUST remain backward compatible with older databases!
+> Users upgrade their Docker containers but keep their existing DB.
+> The app must NOT crash if old columns are missing.
 
-1. **Update schema**: `backend/src/db/schema.ts` - Add the Drizzle column definition
-2. **Update client.ts**: `backend/src/db/client.ts` - Add column to `CREATE TABLE IF NOT EXISTS`
-3. **Update migrate.ts**: `backend/src/db/migrate.ts` - Same as client.ts
-4. **Delete old DB**: `rm backend/data/medassist-ng.db` and restart
+### ⚠️ MANDATORY for EVERY New Feature
+
+**Before implementing ANY feature that touches user data or settings:**
+
+1. **Check if new DB columns are needed** - Does the feature require storing new data?
+2. **If YES → Follow ALL steps below** - Schema.ts + Drizzle migration + ALTER migration + NULL-safe code
+3. **NEVER skip the ALTER migration** - This is the #1 cause of production 500 errors!
+
+**Common mistake:** Adding a column to `schema.ts` and forgetting the ALTER migration in `client.ts`.
+The Drizzle migration only works for NEW databases. Existing production databases need the ALTER migration!
+
+### Schema Management with Drizzle Kit
+
+The database schema uses **Drizzle Kit** for migrations. There is a **single source of truth**:
+
+- **`backend/src/db/schema.ts`** - Drizzle ORM schema definitions (TypeScript)
+- **`backend/drizzle/`** - Generated SQL migrations (auto-generated from schema.ts)
+
+**DO NOT manually edit migration files!** They are generated from schema.ts.
+
+### Adding New Columns
+
+1. **Add to schema.ts** with DEFAULT value:
+   ```typescript
+   maxNaggingReminders: integer("max_nagging_reminders").notNull().default(5),
+   ```
+
+2. **Generate migration**:
+   ```bash
+   cd backend && npx drizzle-kit generate --name add_column_name
+   ```
+
+3. **Add backward-compatible ALTER migration** in `client.ts` `runAlterMigrations()`:
+   ```typescript
+   `ALTER TABLE user_settings ADD COLUMN max_nagging_reminders integer NOT NULL DEFAULT 5`,
+   ```
+
+4. **NULL-safe reading** in routes:
+   ```typescript
+   maxNaggingReminders: settings.maxNaggingReminders ?? 5,
+   ```
+
+### Rules for New Columns
+
+1. **ALWAYS with DEFAULT value**: New columns must have `NOT NULL DEFAULT <value>`
+2. **NULL-safe in code**: All queries must use `?? defaultValue` or `?? false`
+3. **Generate migration**: Run `npx drizzle-kit generate` after schema changes
+4. **Add ALTER migration**: For backward compatibility with existing DBs
+
+### What is NOT Allowed
+
+- ❌ Deleting or renaming columns (breaks old DBs)
+- ❌ `NOT NULL` without `DEFAULT` (INSERT fails)
+- ❌ Reading columns without fallback in code
+- ❌ Manually editing migration SQL files
+- ❌ Documenting "delete DB" as a solution
+
+### When Backward Compatibility is NOT Possible
+
+If a breaking change is unavoidable:
+1. **Explicitly communicate**: Document in release notes
+2. **Migration script**: Provide automatic upgrade script
+3. **Version check**: App should check DB version and warn
