Ruben Fiszel 65f0070fc0 fix: add partial index for fast failure filtering on runs page (#8150)
When failures are sparse (<1%), filtering by failure status on the runs
page required scanning millions of success rows. Add a partial index on
v2_job_completed (workspace_id, completed_at DESC) WHERE status IN
('failure', 'canceled') and switch ORDER BY to completed_at when
filtering failures, so Postgres walks the small partial index directly.

Benchmarked at 5.2M rows / 1% failure rate:
- LIMIT 30:   800ms -> 0.4ms (2000x faster)
- LIMIT 1000: 550ms -> 21ms  (26x faster)
