fix: correct dose ID generation for empty takenBy arrays (#105)

The takenBy field is a string[]. Empty arrays [] are truthy in JavaScript,
causing d.takenBy ? [...] patterns to generate dose IDs with trailing
hyphens (e.g., '5-0-173...-') instead of base IDs ('5-0-173...').

This mismatch between ID generation and computeMissedPastDoseIds (which
correctly uses .length > 0) caused doses to always appear as missed.

Changes:
- Add expandDoseIds() helper function using correct .length > 0 check
- Replace 8 buggy inline patterns in DashboardPage.tsx
- Refactor SchedulePage.tsx to use shared expandDoseIds()
- Add backend startup repair to strip trailing hyphens from existing IDs
- Add 12 new tests (6 frontend + 6 backend)

+### Release Workflow (MANDATORY for minor/major releases)
+
+The `main` branch is protected - releases are created via GitHub's release UI or API.
+
+**Release Process:**
+1. Create a new release on GitHub with tag `vX.Y.Z`
+2. **Automatic Version Bump**: A GitHub Action (`version-bump.yml`) automatically updates `package.json` versions to match the release tag
+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 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.

+- **UI Consistency**: Always use existing components for modals, buttons, and forms. For confirmation dialogs, use `ConfirmModal` component. Never create inline modals with custom button styling - all UI elements must match the existing design system. When adding new sections to existing components, ensure font sizes, spacing, margins, and button styles match exactly with other sections. Check existing CSS classes before creating new ones.

+### ⚠️ 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**:
