Merge pull request 'fix: pass --config to filebrowser (v2.63.x changed default lookup path)' (#5) from fix/filebrowser-config-args into main

The previous PR pinned filebrowser to v2.63.13 + runAsUser:0 which
solved the PVC permission issue, but the pod was still 0/1 Ready
because v2.63.x changed the default config-file lookup path:

  Old (v2-alpine): /.filebrowser.json (matched our existing mount)
  New (v2.63.13) : /config/settings.json (NOT mounted in this pod)

So the new image ran with its built-in defaults (port 80, in-memory
db), and the readiness probe on 8080/health timed out.

Fix: pass `args: ["-c", "/.filebrowser.json"]` so filebrowser uses the
ConfigMap we already mount there. No volumeMount changes needed.
