Several Actions code paths issued one or more queries per listed row.
They now load in batch, with unchanged output.
- API job list: tasks, steps and runners load in batch
- API run list: latest attempts and their trigger users load in batch
- Repository runs page: the jobs of all active runs load in one query
- Cancelling previous runs and replacing concurrency group entries fetch
their jobs in one query
Per call with 50 rows on SQLite, base vs head:
| Path | Queries | Time |
| --- | --- | --- |
| API job list | 254 → 6 | 12.9 → 1.9 ms |
| API run list | 305 → 207 | 11.7 → 6.2 ms |
| Runs page job loading | 100 → 1 | 6.5 → 0.47 ms |
| `CancelPreviousJobs` | 546 → 496 | ~120 ms, per-job writes dominate |
The remaining run list queries come from per-run repository conversion,
which this PR doesn't change.
