Barman Cloud CNPG-I backup plugin

After a failover/promotion, WAL archiving permanently breaks because barman-cloud-check-wal-archive rejects the archive with "Expected empty archive" -- it finds WAL from the previous timeline and treats it as an error. Detect the server's current timeline from pg_controldata (reliable because PostgreSQL's end-of-recovery checkpoint updates the control file before the archiver starts) and pass it via --timeline to the check command. WAL from earlier timelines is then accepted as expected, while WAL from the current timeline in the archive still correctly triggers the safety check. Timeline detection is scoped strictly inside the one-time empty-archive check gate (.check-empty-wal-archive flag file). Steady-state WAL archiving is completely unaffected. During restore/bootstrap, timeline 0 is passed so the check remains strict (archive must be empty).
