fix(bash): zbackup treats a not-running local DB as a calm skip

Fold all pg_dump messaging into local_pg_dump (caller just captures
success) and special-case an unreachable database. "connection refused"
/ "could not connect" / DNS / timeout now print a quiet
"Local database not running at host:port - source-only backup." instead
of a red multi-line error - a stopped dev DB is a normal state. Real
failures (version mismatch, auth, missing db) still print the full
pg_dump error so they're diagnosable.
