Ruben Fiszel 03c87a9d05 test(queue): simulated-workload integration tests for workspace fairness ...

Validates the cloud workspace-fairness algorithm on representative workloads:

- `fairness_caps_dominant_workspace` — a workspace with ~85% of cluster
  throughput is the only one flagged as overloaded.
- `fairness_respects_min_total` — below `min_total`, no cap fires even at
  100% share (avoids throttling a cluster running a single job).
- `fairness_pull_query_skips_capped_workspace` — with the overloaded set
  populated, the fairness pull SQL skips the capped workspace's queued
  jobs while the regular SQL would still pick them up.
- `fairness_lifts_when_load_drops` — cap clears once the noisy
  workspace's share falls under the threshold.
- `fairness_catches_slot_hoggers` — long-running jobs (running=true,
  zero completed in window) trip the cap just like high-throughput tiny
  jobs.

Required exposing `refresh_overloaded` (was `pub(self)`) so the
integration test crate can drive a refresh without going through the
cloud-host gate in `maybe_refresh_overloaded`.
