Daniel Volz ba36f67371 fix: smooth mobile edit transition and align modal validation behavior (#286)
* fix: reliable Escape key close for all modals via useEscapeKey hook

- Add useEscapeKey hook (document-level keydown listener)
- Retrofit all 12 modal/overlay components to use it
- Remove redundant overlay onKeyDown Escape handlers
- Simplify modal-content onKeyDown to plain stopPropagation
- Replace MedDetailModal's capture-phase useEffect with 3 useEscapeKey calls
- Replace SharedSchedule's inline useEffect with useEscapeKey
- Add mandatory modal rules to UI Consistency skill
- All 777 frontend + 569 backend tests pass

* fix: smooth mobile edit transition and align modal validation behavior

* fix: keep overlay keydown non-closing for Enter key

* fix: show mobile name error when validation already exists

* fix: restore app-level escape priority handling

* fix: prioritize schedule lightbox on Escape

# Skill Instructions
Use this skill when implementing or editing UI flows, modals, buttons, forms, schedule views, or settings screens.
## Scope
This is the **guardrail skill** for UI work.
Use it to enforce consistency and prevent design drift.
Use `medassist-frontend-polish` only after these guardrails are satisfied.
## Do Not Use This Skill For
- Creative visual redesign requests where no product consistency constraints apply.
- Marketing-style one-off pages outside MedAssist product UI conventions.
## Rules
- Reuse existing components (for example `ConfirmModal`, `MedicationAvatar`) before creating new primitives.
- Keep spacing, typography, and button styles aligned with existing patterns.
- Avoid custom inline modal/button patterns that diverge from project design.
- Prefer extending existing CSS classes/styles instead of introducing parallel styling systems.
### Modal requirements (non-negotiable)
Every modal/overlay **must** follow these rules:
1. **Escape key**: Call `useEscapeKey(active, onClose)` from `hooks/useEscapeKey`. This registers a document-level `keydown` listener that works regardless of focus. **Never** rely on `onKeyDown` on an overlay div — it only fires when the overlay has focus, which almost never happens.
2. **Scroll lock**: Call `useScrollLock(active)` from `hooks/useScrollLock` if the modal is **not** already covered by App.tsx's centralized `useScrollLock` call. Page-local modals (e.g. `ReportModal`, `ExportModal`) must call it themselves.
3. **Click-outside close**: The overlay div gets `onClick={onClose}`, and `.modal-content` gets `onClick={(e) => e.stopPropagation()}`.
4. **Key event containment**: `.modal-content` gets `onKeyDown={(e) => { if (e.key !== "Escape") e.stopPropagation(); }}` — this prevents non-Escape keys from leaking out while still allowing Escape to propagate to the document-level handler.
5. **Nested sub-modals** (e.g. edit-stock inside MedDetailModal): Use `useEscapeKey` with `{ capture: true }` so the innermost modal intercepts Escape before the parent's handler fires.
## Decision Heuristics
1. If an equivalent component exists, reuse it.
2. If small variant is needed, extend existing styles minimally.
3. If a new component is unavoidable, match existing naming and structure conventions.
## Response Format
Provide:
- Reused components/styles
- Any new UI element and why reuse was not possible
- Consistency risks reviewed
- Confirmation that `medassist-frontend-polish` constraints remain compatible (if polish work is also requested)
