Add an admin 'Pull & rebuild' button (Settings → Updates). It POSTs an
admin-gated route that signals a privileged 'updater' sidecar (adnanh/webhook +
docker socket) over the internal network with a shared secret; the sidecar runs
'git fetch && reset --hard origin/master && docker compose up -d --build app'
detached. The UI polls /api/version until the rebuilt app returns on the new
version, then reloads.
Secret matching uses webhook -template + getenv so UPDATER_SECRET stays out of
the repo (host .env only). No request data reaches the shell — the command is
fixed in updater/update.sh.
