Merge feature/v1.5: Supabase entfernt, vollständig selbst gehostet

Postgres statt Supabase-Cloud, eigene Session-/Passkey-Auth, lokale
Branding-Dateiablage, Autorisierung in den API-Routen statt RLS,
automatischer Admin-Bootstrap bei leerer Datenbank, Gerichtsuche im
Wochenplan. Vor dem Merge per Sicherheitsprüfung geprüft, ein
gefundenes SVG-Upload-XSS-Problem behoben.

+## [1.5.0] – 2026-07-18
+
+### Hinzugefügt
+- Wochenplan: „Mahlzeit hinzufügen" bietet jetzt ein Suchfeld mit
+  gefilterter Trefferliste statt einer langen Dropdown-Liste zum
+  Durchscrollen.
+- `db/seed-demo.sql` (`npm run db:seed-demo`): spielt für lokale
+  Entwicklung/Demos den ursprünglichen Beispieldatensatz ein
+  (Essenszeiten, Allergene, Zusatzstoffe, Testgerichte, zwei
+  Beispielwochen) – kein Teil der automatischen Migrationen, frische
+  Deployments starten weiterhin leer.
+
+### Geändert
+- **Supabase vollständig entfernt** – die App läuft jetzt komplett
+  selbst gehostet, einzige externe Abhängigkeit bleibt optional DeepL.
+  - Datenbank: selbst gehostetes PostgreSQL statt Supabase-Cloud-Postgres.
+    Schema in `db/migrations/*.sql`, wird beim Start automatisch und
+    idempotent angewendet (`db/migrate.mjs`).
+  - Anmeldung: eigene Session-Verwaltung (opake, in der DB gespeicherte
+    Tokens, `httpOnly`/`sameSite=lax`-Cookie) statt Supabase Auth.
+    Passwörter werden mit Node-eigenem `crypto.scrypt` gehasht (keine
+    neue Abhängigkeit).
+  - Passkeys: `@simplewebauthn` ersetzt Supabase's bisher experimentelles
+    WebAuthn-API. Die RP-Domain wird direkt aus `APP_URL` abgeleitet –
+    kein externer Konfigurationsschritt mehr nötig.
+  - Logo/Favicon: lokale Dateiablage (Docker-Volume) statt
+    Supabase-Storage-Bucket, ausgeliefert über `/branding/[filename]`.
+  - Autorisierung (öffentlich lesbar / Kantinen-Team schreibt / nur
+    Admin für Einstellungen & Benutzer) läuft jetzt in den API-Routen
+    statt über Postgres-Row-Level-Security.
+  - E-Mail-Änderung im eigenen Konto läuft direkt nach
+    Passwort-Bestätigung statt über eine Supabase-Bestätigungsmail
+    (kein SMTP-Server vorhanden).
+- Datenbank startet beim allerersten Deployment leer; beim ersten Start
+  wird automatisch genau ein Admin-Benutzer mit zufällig generiertem
+  Passwort angelegt, die Zugangsdaten landen in `ZUGANGSDATEN.md`.
+
+### Behoben
+- „Mindestens 1 Passkey nötig, um die Passwort-Anmeldung zu
+  deaktivieren" wurde bisher nur clientseitig geprüft; ein manuell
+  gebauter Request hätte die Passwort-Anmeldung auch ohne Passkey
+  deaktivieren können. Jetzt zusätzlich serverseitig erzwungen.
+- Logo-/Favicon-Upload akzeptierte anhand des vom Browser gemeldeten
+  Dateityps auch SVG-Dateien. Da diese (anders als beim vorherigen
+  Supabase-Storage-Bucket auf fremder Domain) jetzt auf der eigenen
+  Origin ausgeliefert werden, hätte eine SVG mit eingebettetem
+  `<script>` bei direktem Aufruf der Datei-URL im Browser eines
+  anderen angemeldeten Admins ausgeführt werden können. Upload
+  akzeptiert jetzt nur noch eine Whitelist an Rasterformaten
+  (png/jpg/webp/gif/ico); vor dem Merge im Rahmen der
+  Sicherheitsprüfung gefunden und behoben.
+
+### Hinweis für bestehende Docker-Installationen
+Das Docker-Volume `pgdata` diente bisher nur als Lese-Kopie/Backup und
+wird mit v1.5 zur primären Datenbank. Es enthält noch das alte
+Supabase-Mirror-Schema und muss vor dem Upgrade entfernt werden
+(`docker compose down -v`, danach `docker compose up -d --build`), damit
+die neuen Migrationen auf einer leeren Datenbank laufen.
+
+## [1.4.0] – 2026-07-18
+
+### Hinzugefügt
+- Essenszeiten (Brotzeit/Mittagessen/…) vollständig verwaltbar: anlegen,
+  umbenennen (inkl. EN/PL), Uhrzeit ändern, löschen und per Pfeil-Buttons
+  neu anordnen – neue Seite „Essenszeiten" im Kantinen-Bereich. Löschen
+  entfernt zugewiesene Gerichte automatisch aus allen Wochenplänen.
+
+### Geändert
+- „Automatisch übersetzen"-Button bei Gerichten/Allergenen/Zusatzstoffen
+  ist nur noch sichtbar, wenn `DEEPL_API_KEY` gesetzt ist, statt erst
+  nach Klick auf die fehlende Konfiguration hinzuweisen.
+
+### Behoben
+- Sprachumschalter (DE/EN/PL) erschien auf der öffentlichen Speisekarte
+  in der mobilen Ansicht doppelt.
+

 ## Datenbank
 
-### Supabase (führende Datenbank)
+Reines PostgreSQL (kein Supabase, keine Row-Level-Security-Policies) –
+alle Zugriffsrechte werden in den Route-Handlern geprüft (`lib/auth/session.ts`,
+`requireRole`).
 
-- Projekt-Ref: `hvzikwjoyhoakedlywhj` (Region `eu-central-1`, Frankfurt)
-- Schema und Seed-Daten: `supabase/migrations/0001_init.sql` und `0002_seed.sql`
-- Ausführen weiterer SQL-Dateien:
-  `SUPABASE_ACCESS_TOKEN=<token> node scripts/db-apply.mjs <datei.sql>`
+- Schema: `db/migrations/*.sql`, nummeriert, wird von `db/migrate.mjs`
+  automatisch angewendet (idempotent, bei jedem Start des Servers bzw.
+  Docker-Containers).
+- Neue Migration hinzufügen: `db/migrations/000N_beschreibung.sql`
+  anlegen, wird beim nächsten Start automatisch eingespielt.
+- Manuell migrieren: `npm run db:migrate`
 
-Sicherheitsmodell (Row Level Security):
+Rechte-Modell (in Anwendungscode statt Datenbank-RLS):
 
-- `anon` darf ausschließlich lesen (Speisekarte, Bereiche, Allergene,
-  Zusatzstoffe, Einstellungen).
-- `staff`/`admin` (Rolle im `profiles`-Eintrag) pflegen Gerichte,
-  Wochenplan und Kennzeichnungen.
-- Nur `admin` ändert Einstellungen (Farben/Logo) und verwaltet Benutzer;
-  das Anlegen/Löschen von Benutzern läuft serverseitig über den
-  Service-Role-Key (`app/api/admin/users`).
-- Storage-Bucket `branding` (Logo): öffentlich lesbar, Schreibzugriff nur Admin.
-
-### Lokale PostgreSQL-Kopie
-
-Die Datenbank `canteen_menu` (Kopie von Schema + Daten aus Supabase, inkl.
-Minimal-Stubs für `auth`/`storage`) gibt es in zwei Varianten:
-
-**Per Docker:** Der Dienst `db` aus `docker-compose.yml` spielt die
-Skripte aus `supabase/local/` beim ersten Start automatisch ein
-(PostgreSQL 17, Host-Port 5433 – 5432 ist meist durch eine native
-PostgreSQL-Installation belegt –, Passwort über `LOCAL_PG_PASSWORD`).
-
-**Nativ:** Auf dem Entwicklungsrechner läuft PostgreSQL 17 mit derselben
-Datenbank. Neu aufbauen bzw. aktualisieren:
-
-```powershell
-$env:SUPABASE_DB_PASSWORD = "<Supabase-DB-Passwort>"
-$env:LOCAL_PG_PASSWORD    = "<lokales postgres-Passwort>"
-powershell -File scripts\sync-local-db.ps1
-```
-
-Hinweis: Die lokale Kopie dient als Ablage/Backup und für Auswertungen.
-Logins (Passwort-Hashes, Passkeys) verbleiben ausschließlich in Supabase.
+- Öffentlich lesbar (kein Login nötig): Speisekarte, Essenszeiten,
+  Allergene, Zusatzstoffe, Logo/Favicon.
+- `staff`/`admin` pflegen Gerichte, Essenszeiten, Wochenplan und
+  Kennzeichnungen.
+- Nur `admin` ändert Einstellungen (Farben/Logo) und verwaltet Benutzer.
