ci: probe whether pmxcfs came up clustered or in local mode

Browse Source 
Run 173 left node B with healthy corosync (2-member primary component, both
links connected) but no /etc/pve/corosync.conf, no dcdb/status journal lines,
and pvecm status reporting it is not part of a cluster. That file is
database-backed: pmxcfs creates it only when it starts with no config.db and
imports /etc/corosync/corosync.conf, so a surviving standalone config.db would
mean silent local mode.

Capture the package versions, pmxcfs command line, /etc/pve mount, .members,
the config.db and its backup dir, whether the database holds a corosync.conf
row, and the CPG group membership. Read-only; the sqlite3 CLI is not guaranteed
on a PVE node, so fall back to strings.
