feat(deploy): public hosting at cannamanage.plate-software.de + fix systemic auth-token bug

Auth fix (the real unblocker):
- Add server-side proxy Route Handler app/api/backend/[...path]/route.ts that
  reads the NextAuth session via auth() and injects Authorization: Bearer on
  every API call. Method-agnostic; streams raw request body (multipart uploads)
  and upstream response body (binary PDF/CSV downloads). Replaces the static
  next.config.mjs rewrite, which could not inject a header — the root cause of
  every authenticated browser fetch hitting the backend unauthenticated.
- Expose session.accessToken in the auth.ts session() callback (+ type aug).
  Uses auth() not getToken() so cookie handling is correct across the public
  HTTPS (Apache) -> internal HTTP (container) proxy boundary.
- No service files changed; all 24 services already call /api/backend/*.
  Verified live: NextAuth login -> GET /api/backend/members -> HTTP 200.

Public hosting (same proven chain as Gitea/InspectFlow):
- docker-compose.truenas.yml: NEXTAUTH_URL/AUTH_URL -> https public origin,
  rotate AUTH_SECRET + JWT_SECRET + DB_PASSWORD off the committed dev defaults.
- deploy.yml: inject AUTH_SECRET/JWT_SECRET/DB_PASSWORD from Gitea secrets;
  reconcile the live Postgres role password (volume keeps old pw on re-deploy).
- frpc on TrueNAS tunnels frontend :3000 -> VPS frps :30010; IONOS Apache
  terminates TLS for cannamanage.plate-software.de and proxies through frp.
