fix(filebrowser_quantum): keep server.database siblings, sanitize direct XFF

Set only server.database.path (dropping migrateFrom) so user-set keys such
as activity survive, and replace X-Forwarded-For on the published 8071
listener now that FileBrowser trusts proxy headers for login rate limits.

   - Users, shares and settings in `/config/database.db` are migrated to `/config/database.sqlite` on first start.
 - `http.trustProxyHeaders` is set to `true`, because the add-on always runs behind nginx on a subpath.
 - The container healthcheck now uses upstream's `/health` endpoint.
+- Direct access on port 8071 no longer passes on a client-supplied `X-Forwarded-For`, so the IP-based login lockout cannot be bypassed now that proxy headers are trusted. Ingress keeps the forwarded chain.
 
 ## 2.0.0 (2026-10-10)
 - Update to latest version from gtsteffaniak/filebrowser (changelog : https://github.com/gtsteffaniak/filebrowser/releases)
