fix(ark): retry the server install before handing over to the image

The image's start_server runs SteamCMD once and carries on even when it
fails; SteamCMD's intermittent "Missing configuration" error then left
no server installed, so ARK exited and only the node's restart policy
saved it (a boot test would fail on the restart). First boot showed it.

The startup command now downloads SteamCMD if missing, runs the usual
"+login anonymous +quit" warm-up and installs app 2430930, retrying up
to three times until ArkAscendedServer.exe exists. start_server's own
install step then only validates.
