feat: add pg_statviz repl and slru collectors

Add collectors for new pg_statviz tables:
- pgstatviz.repl: replication statistics (standby lag, slot stats)
- pgstatviz.slru: SLRU cache statistics

Also standardize all pg_statviz queries to use SELECT * for
consistency and to automatically capture new columns.

Update copyright year to 2026.
