Merge feature/v1.9.5: interner Bereich für Mobilgeräte nutzbar

AppHeader.tsx: Hamburger-Menü unterhalb "sm" mit denselben Links
gestapelt (Vorschläge-Badge-Logik in gemeinsame renderLinks()-Funktion
ausgelagert), Panel schließt automatisch bei Navigation. Bisherige
einzeilige Navigation bleibt ab "sm" unverändert.

WeekEditor.tsx: Mobile Tag-für-Tag-Ansicht mit Tab-Leiste (Mo-Fr)
statt der 6-spaltigen Tabelle, die bei 375px unbenutzbar gequetscht
war. Zellinhalt (Eintragsliste + "hinzufügen"-Flow) in renderCell()
extrahiert und von Tabelle und Karten-Ansicht gemeinsam genutzt, damit
der Bearbeitungs-Zustand nicht dupliziert werden muss. Desktop-Tabelle
unverändert ab "sm".

DishManager/CodeListManager/UserManager/SectionManager/PasskeyManager:
Kopf- und Listenzeilen brechen jetzt bei Bedarf um (flex-wrap) statt
Buttons abzuschneiden, gleiches Muster wie bereits in
SuggestionReview.tsx vorhanden.

Version 1.9.5.

+## [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.
+
+## [1.9.0] – 2026-07-20
+
+### Hinzugefügt
+- SSO-Login per OpenID Connect (z. B. gegen ein selbst gehostetes
+  Authentik), zusätzlich zu Passwort und Passkey. Konfiguration über
+  drei optionale Env-Vars (`OIDC_ISSUER`, `OIDC_CLIENT_ID`,
+  `OIDC_CLIENT_SECRET`) – ohne sie bleibt der SSO-Button auf der
+  Anmeldeseite ausgeblendet. Authorization-Code-Flow mit PKCE, ID-Token-
+  Signaturprüfung gegen das JWKS des Providers (neue Abhängigkeit
+  `jose`), State/Nonce serverseitig kurzlebig und einmalig verwendbar
+  (neue Tabelle `oidc_states`, Migration `0003_oidc_state.sql`).
+  SSO-Login funktioniert ausschließlich für bereits unter „Benutzer“
+  angelegte E-Mail-Adressen – es werden nie neue Konten angelegt, und
+  die Rolle (Admin/Kantinenmitarbeiter) bleibt ausschließlich über die
+  bestehende Benutzerverwaltung steuerbar, nie aus SSO-Claims
+  übernommen. In DEPLOYMENT.md unter „SSO/OpenID Connect“ dokumentiert.
+
+## [1.8.1] – 2026-07-20
+
+### Hinzugefügt
+- `update.sh`: Update-Skript für Linux-Deployments – stoppt den Docker-
+  Stack, sichert lokale Änderungen an `docker-compose.yml` per
+  `git stash` (falls vorhanden), führt `git pull` aus, spielt die
+  Änderungen zurück und startet den Stack neu im Build-Modus. Bricht
+  bei einem `git pull`- oder Stash-Konflikt kontrolliert ab, statt mit
+  einem halb aktualisierten Stand weiterzumachen. In DEPLOYMENT.md unter
+  „Updates einspielen“ dokumentiert.
+
+## [1.8.0] – 2026-07-19
+
+### Hinzugefügt
+- Umschaltbarer Hinweismodus für Allergene/Zusatzstoffe: Auf der Seite
+  „Allergene & Zusatzstoffe“ kann zwischen der bisherigen detaillierten
+  Auswahl je Gericht und einem einfachen, in Deutsch/Englisch/Polnisch
+  editierbaren Hinweistext (z. B. „Bei Fragen zu Allergenen und
+  Zusatzstoffen wenden Sie sich bitte an das Kantinen-Team.“)
+  umgeschaltet werden. Im Hinweismodus entfällt auf der öffentlichen
+  Speisekarte die Legende und die Kürzel an den Gerichten, und in der
+  Gerichte-Verwaltung wird die Allergen-/Zusatzstoff-Auswahl beim
+  Bearbeiten ausgeblendet (bereits zugeordnete Daten bleiben in der
+  Datenbank erhalten). Umschalten und Hinweistext bearbeiten dürfen
+  sowohl Kantinenpersonal als auch Admins.
+
+## [1.7.0] – 2026-07-19
+
+### Hinzugefügt
+- CSV-Import/-Export für Gerichte, Allergene und Zusatzstoffe (Buttons
+  „Exportieren“/„Importieren“ auf den jeweiligen Verwaltungsseiten).
+  Export lädt die aktuelle Liste als CSV herunter (Gerichte:
+  `name,name_en,name_pl,price,allergens,additives`, Allergene/
+  Zusatzstoffe: `code,name,name_en,name_pl`; Kürzel bei Gerichten
+  Semikolon-getrennt in einer Zelle, z. B. `A;G`). Import liest dieselbe
+  Spaltenstruktur (Reihenfolge egal, Groß-/Kleinschreibung der
+  Kopfzeile wird ignoriert) und aktualisiert bestehende Einträge
+  (Abgleich über Kürzel bei Allergenen/Zusatzstoffen, über den exakten
+  Namen bei Gerichten) bzw. legt neue an. Zeilen mit fehlenden
+  Pflichtfeldern, ungültigem Preis oder mehrdeutigem Gerichtsnamen
+  (mehrere Gerichte mit demselben Namen) werden übersprungen und mit
+  Grund in der Erfolgsmeldung aufgelistet, statt den ganzen Import
+  abzubrechen.
+
+### Behoben
+- RSS-Feed (`/feed.xml`): Mehrere Feed-Reader (u. a. Outlook,
+  Thunderbird) behandeln `<description>` als kurze Vorschau und kürzen
+  sie eigenmächtig – dadurch war bei Tagen mit mehreren Essenszeiten
+  oft nur die erste sichtbar, obwohl der Server bereits alle
+  Essenszeiten des Tages in der Beschreibung lieferte. Zusätzlich zu
+  `<description>` wird jetzt auch `<content:encoded>` (RSS-Content-
+  Modul) mit demselben vollständigen Inhalt ausgeliefert – von den
+  meisten Readern als vollständiger Artikeltext erkannt und ungekürzt
+  angezeigt.

+## SSO/OpenID Connect (optional)
+
+Zusätzlich zu Passwort und Passkey kann ein SSO-Login gegen einen
+beliebigen OpenID-Connect-Provider aktiviert werden (z. B. ein selbst
+gehostetes [Authentik](https://goauthentik.io/)). Dazu in `.env.local`
+setzen:

+OIDC_CLIENT_ID=<client-id-aus-authentik>

+Beim Identity Provider als Redirect-URI hinterlegen:
+`<APP_URL>/api/auth/oidc/callback` (also z. B.

+
+**Wichtig:** SSO-Login funktioniert ausschließlich für E-Mail-Adressen,
+die bereits unter „Benutzer“ angelegt sind – es werden nie neue Konten
+angelegt, und die Rolle (Admin/Kantinenmitarbeiter) bleibt ausschließlich
+dort steuerbar. Ein Mitarbeiter muss also zuerst ganz normal als
+Benutzer angelegt werden, bevor er sich per SSO anmelden kann.
+
+Ohne die drei Variablen bleibt der SSO-Button auf der Anmeldeseite
+einfach ausgeblendet, Passwort/Passkey funktionieren unverändert.
