The mmmaxwwwell SE image calls steamcmd with +login before +force_install_dir,
which Steam rejects ("Please use force_install_dir before logon!"), so container
restarts never actually update the game. The new handler runs SteamCMD in a
sibling one-shot container with the correct argument order, mounting the same
volumes as the live container, then leaves the server stopped for the operator
to start. The version cache is invalidated after a successful update so the UI
shows the new build immediately.

Reads the SteamCMD appmanifest_298740.acf via SSH and exposes
buildid + LastUpdated through a new /api/servers/:id/version endpoint.
The overview tab now renders a "Server Version" card and surfaces a
pending update hint when TargetBuildID differs from the installed build.
