fix(monitoring): add _total suffix to PostgreSQL counter metrics in Grafana dashboard (#1485)
Align metric names with Prometheus naming conventions by appending _total suffix to pg_stat_database counter metrics (tup_inserted, tup_updated, tup_deleted, tup_fetched, tup_returned, blks_hit, blks_read, conflicts, deadlocks, temp_bytes).
