Add a host-watcher-backed update button on Version & Releases. The container
(no Docker socket) writes an update sentinel; a new root-run systemd unit
(clusev-update.path/.service) runs watch.sh update -> update.sh (git pull +
idempotent install). The sentinel is consumed before running so a persistent
failure can't loop the path unit.
The button only appears once a check finds a newer release, is per-user
throttled (3/10min, auto-expiring) and audited (deploy.update_request); the UI
warns the dashboard is briefly down during the rebuild. install.sh now installs
both the restart and update host units (update unit runs as root for
docker/systemd/apt).

The update check read the newest release tag from local .git, which the
production Docker image does not contain — so 'check for updates' always
reported 'no release tagged' in prod even when a newer version existed. It now
queries the public, read-only Gitea tags API (anonymous; no token leaves the
panel), keeps local .git only as a dev fallback, and caches the result so a
page render never makes a network call (only the explicit action does).
Channel-aware (stable = vX.Y.Z only; beta also sees prereleases) and degrades
silently when the host is unreachable.
