Merge feature/v1.10.0: Dynamisches Sprachpaket-System für die Bedienoberfläche

Teil 1 des "mehrsprachig variabel"-Umbaus (Speiseplan-Inhalte folgen
in einer späteren Version). Sprachen sind jetzt zur Laufzeit über eine
neue Admin-Seite "Sprachen" verwaltbar statt fest im Code zu stehen:

- Neue Tabellen languages/ui_translations (Migration 0004), bestehende
  Englisch-/Polnisch-Texte per generiertem Seed automatisch übernommen
  (Migration 0005) - keine manuelle Nacharbeit, nichts geht verloren.
- lib/i18n/flatten.ts: verschachtelte Dict-Objekte (inkl. Arrays wie
  weekdays.long) <-> flache Schlüssel-Wert-Paare, Basis für Vorlage-
  Export/-Import.
- lib/i18n/template.ts: Vollständigkeits-/Veraltet-Berechnung (Hash
  über die DE-Schlüsselliste) und Import-Validierung (Platzhalter wie
  {message} müssen erhalten bleiben, unbekannte Schlüssel werden
  ignoriert statt Fehler zu werfen).
- getDictionary()/getLocale() (lib/i18n/index.ts) jetzt asynchron und
  DB-gestützt für Nicht-Basis-Sprachen, mit Fallback auf Deutsch für
  fehlende Schlüssel. Locale-Typ bewusst von festem TypeScript-Tupel
  auf string generalisiert (Kompromiss: Compiler prüft Vollständigkeit
  nicht mehr automatisch, das übernimmt jetzt die Veraltet-Erkennung
  zur Laufzeit).
- LanguageSwitcher/LocaleProvider lesen aktive Sprachen jetzt aus dem
  Context statt aus einer festen Konstante; blendet sich bei nur einer
  aktiven Sprache automatisch aus.
- Neue Admin-Routen app/api/admin/languages/* (Liste inkl.
  Vollständigkeit, Anlegen, Aktivieren/Deaktivieren mit
  "mindestens eine muss aktiv bleiben"-Schutz, Löschen außer
  Basis-Sprache, Vorlage-Download, Datei-Import) + LanguageManager.tsx.

Vollständig gegen echten DB-Zustand getestet: Vorlage-Export/-Import
inkl. Platzhalter-Validierung, neue Sprache anlegen, auf eine Sprache
reduzieren (Umschalter verschwindet, "letzte Sprache"-Schutz greift),
Veraltet-Erkennung nach simuliertem neuen Schlüssel, Cascade-Delete.

Version 1.10.0.

+## [1.10.0] – 2026-07-20
+
+### Hinzugefügt
+- Dynamisches Sprachpaket-System für die Bedienoberfläche (Teil 1 des
+  "mehrsprachig variabel"-Umbaus, Speiseplan-Inhalte folgen in einer
+  späteren Version). Sprachen sind jetzt zur Laufzeit über eine neue
+  Admin-Seite „Sprachen" verwaltbar statt fest im Code zu stehen:
+  - Vorlage der aktuellen deutschen Texte herunterladen, übersetzt
+    wieder hochladen – neue Übersetzungen werden sofort aktiv, ohne
+    Deployment.
+  - Fehlende Begriffe fallen automatisch auf Deutsch zurück statt leer
+    zu bleiben; die Admin-Seite zeigt pro Sprache Vollständigkeit in %
+    sowie „N neue Begriffe seit letztem Import", falls eine neue
+    App-Version zusätzliche Texte eingeführt hat.
+  - Sprachen lassen sich einzeln deaktivieren, bis auf eine einzige
+    reduzierbar (der Sprachumschalter blendet sich dann automatisch
+    aus) – mindestens eine muss aktiv bleiben.
+  - Neue Sprachen lassen sich direkt anlegen (Code + Anzeigename),
+    Deutsch bleibt als einzige garantiert vollständige Basis-Sprache
+    unlöschbar.
+  - Import validiert hochgeladene Übersetzungen gegen die aktuelle
+    Vorlage: Platzhalter wie `{message}` müssen erhalten bleiben,
+    unbekannte Schlüssel werden ignoriert statt Fehler zu werfen.
+  - Neue Tabellen `languages`/`ui_translations` (Migration `0004`),
+    bestehende Englisch-/Polnisch-Texte automatisch übernommen
+    (Migration `0005`) – keine manuelle Nacharbeit nötig.
+
+## [1.9.5] – 2026-07-20
+
+### Hinzugefügt
+- Interner Bereich (Wochenplan, Essenszeiten, Gerichte, Allergene &
+  Zusatzstoffe, Vorschläge, Benutzer, Design, Mein Konto) für
+  Mobilgeräte nutzbar gemacht. `AppHeader.tsx` bekommt unterhalb der
+  `sm`-Breakpoint-Grenze ein Hamburger-Menü mit denselben Links
+  gestapelt statt der bisherigen, bei schmalen Bildschirmen unübersichtlich
+  umbrechenden einzeiligen Navigation. Der Wochenplan (`WeekEditor.tsx`)
+  zeigt auf Mobilgeräten eine Tag-für-Tag-Ansicht mit Tab-Leiste
+  (Mo–Fr) statt der für 375px viel zu schmalen 6-spaltigen Tabelle –
+  Gericht hinzufügen/löschen funktioniert unverändert, da beide
+  Ansichten denselben Bearbeitungs-Zustand teilen. In DishManager,
+  CodeListManager, UserManager, SectionManager und PasskeyManager
+  brechen Kopf- und Listenzeilen jetzt bei Bedarf um, statt Buttons
+  abzuschneiden.
+
