feat: Phase 2 Schritt 11+12 — Essensplan-Modul + Einkaufslisten-Integration
- server/routes/meals.js: vollständige REST-API (GET Woche, POST/PUT/DELETE Mahlzeit, POST/PATCH/DELETE Zutaten, GET Autocomplete-Suggestions, POST to-shopping-list, POST week-to-shopping-list) - public/pages/meals.js: Wochengitter (Mo–So × 4 Mahlzeit-Typen), Navigations-Buttons, CRUD-Modal mit Autocomplete, Zutaten-Verwaltung, Einkaufslisten-Transfer-Button - public/styles/meals.css: Wochengitter, Slot-Karten, Modal-Overlay, Zutaten-Zeilen, Transfer-Panel, Typ-Farben - test-meals.js: 22 Tests (CRUD, Wochensortierung, Constraint, CASCADE, Integration, Autocomplete, Wochenberechnung) - package.json: test:meals + Gesamt-Test-Suite erweitert - public/index.html: meals.css eingebunden Gesamt: 93 Tests bestanden (29 DB + 8 Dashboard + 17 Tasks + 17 Shopping + 22 Meals) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
