Subject: [PATCH] FN-7464: speed up insights route retry tests

Collapse deliberate retry waits in the insights route test suite while preserving retry coverage.

- Mock node:timers/promises in insights route tests so retry backoff resolves immediately.
- Document the FN-7464 performance rationale with an FNXC dashboard test comment.

+FN-7464 measured the only remaining slow test-body seam as retryable insight-route failures waiting the production 250ms retry delay from node:timers/promises. Keep route-boundary retry coverage and assertions intact, but collapse that deliberate backoff in this file so the suite does not spend real wall time on retry pacing.
