perf(config): lower default fetch_interval_max from 60s to 5s (#875)

## Summary

- Lower the default `fetch_interval_max` from 60s to 5s to reduce job pickup latency for common single-runner deployments
- PR #819 optimized defaults for 200-runner fleets, regressing single-runner pickup time from ~2s to ~65s
- Most deployments use few runners; large fleets can still tune this value higher in their config

## Impact

| `fetch_interval_max` | 1 runner pickup | 200 runners idle |
| -------------------- | --------------- | ---------------- |
| 60s (previous)       | up to **65s**   | 3.3 req/s        |
| **5s (new default)** | up to **5s**    | 40 req/s         |
