fix(ha/cluster-init): detect StandAlone DRBD state in sync wait loop
Check NixOS configurations / eval-hosts (push) Successful in 10m21s
Details

Browse Source 
If the DRBD peer connection drops during the initial sync wait (cs:StandAlone),
the loop would spin forever printing "waiting for sync progress" with no
indication of what's wrong. Now parses cs: from /proc/drbd each tick and
dies with a clear error if StandAlone is detected. Also shows the cs: field
in the non-syncing message so the actual connection state is always visible.
