Containly 2.7.4

Fixed

• Backups failed with "No such image: alpine:latest" when the helper image was removed from the
  host. Containly checked its backup helper image only once per process: after an image prune or
  a host cleanup removed it later, the image was never pulled again and every backup (scheduled
  and manual) failed with (HTTP code 404) no such container - No such image: alpine:latest until
  Containly was restarted. The helper image is now checked before every use and pulled again when
  it is missing; if it disappears between the check and the start of the helper, Containly pulls
  it once more and retries. Concurrent backups still share one pull.
• Helper image pinned. Backup, restore, folder browser and volume file helpers no longer use
  the moving alpine:latest tag but a pinned Alpine 3.22.2 image by its multi-arch digest (the
  same image the NFS target already used), so every host runs the same known tools. The helpers
  keep their ch.amslertec.containly.helper label. The Docker CLI helper is re-checked and
  re-pulled the same way.

Changed

• Empty states centred. Empty states (for example Updates > "All up to date", empty lists,
  no search hits, empty backup sections, settings tabs) now sit centred as one block, icon, title,
  text and button, horizontally and vertically in the free content area instead of top-left, the
  same on every page, on desktop and phone, in light and dark mode.

Update: docker compose pull && docker compose up -d (or pull amslertec/containly:2.7.4).
