Add updater_check/apply/apply_all/rollback cases to task-router routeAction
and the matching task-actions methods, each running the locked-down
'libreportal updater …' CLI as a task (apply/rollback snapshot-before-update
host-side for disaster recovery). Verified: /updater + all tabs render, the
new Updates nav button shows globally, and the feature auto-discovers via
/api/features/list.
