Merge pull request 'fix: revert filebrowser to v2-alpine (PVC permission issue with v2.63.13)' (#2) from fix/filebrowser-revert into main

The previous PR pinned `filebrowser/filebrowser:v2-alpine` to v2.63.13
but it crashlooped on:

  Error: open /database/filebrowser.db: permission denied

The v2.63.13 image (debian-based default) runs as a non-root UID and
can't write to files on the PVC that were created by the v2-alpine
image (which ran as root). No `v2.63.13-alpine` tag exists upstream
(filebrowser stopped publishing per-version alpine variants), so we
can't trivially preserve the same runtime.

Quick recovery: revert to v2-alpine so filebrowser is usable again.
Proper fix (deferred): either an initContainer that `chown -R 1000:1000
/database /srv` or a `securityContext.fsGroup: 1000` on the pod spec
to let the non-root UID write to the existing PVC. Both require some
care since the chown is destructive if the UID is wrong.
