Ruben FiszelandClaude Opus 4.8 6d94865109 fix: optimize cleanup_job_perms_orphaned and job_result_stream cleanup queries (#9727)
The job_perms/job_result_stream_v2 orphan cleanups in monitor_db used
`NOT IN` anti-joins, `RETURNING job_id` + `fetch_all` (loading every deleted
UUID into memory) and no batch limit. On high-throughput instances these
tables can accumulate tens of millions of orphaned rows, so a single execution
ran for ~298s; because monitor_db awaits each iteration, the cleanup ran
effectively continuously, saturating DB I/O and starving audit partition
creation.

Rewrite both deletes as bounded `NOT EXISTS` anti-joins selecting `ctid` with
a LIMIT 100000, executed via `.execute()` (using rows_affected instead of
fetch_all). Each run is now fast and bounded, while the 30s monitor cadence is
preserved so the tables keep draining promptly.

Fixes WIN-2088
