markmorado e67f6b7249 fix(update): recover from stalled panel self-update instead of hanging at 80% ...

The panel update status lived only in-memory and was cleared solely by the
host watchdog restarting the container. If the rebuild failed mid-way (e.g. the
build OOMs the host when no swap is configured), the container never restarted
and the UI stayed at "restarting - 80%" forever.

- update_service: get_update_status() now self-heals — after UPDATE_TIMEOUT_SECONDS
  (default 900s) of "is_updating" it transitions to a terminal "failed" state with
  a clear error pointing at the host update service / logs.
- use-settings: poll update status while the server reports is_updating (not only
  right after the click in the same tab), so reloading a stuck page keeps refreshing.
- SettingsPage: banner now renders the "failed" state with the error message.
- update_host.sh: build images sequentially (app, then frontend) to lower peak
  memory and avoid the OOM that killed the build mid-run.
