OCPBUGS-113581: Raise status polling timeout and write bound

[redhat-chai-bot]

Summary

Cherry-pick of #31534 to release-4.20.

Fixes flaky test [sig-network][Feature:Router] The HAProxy router converges when multiple routers are writing conflicting status by raising two thresholds in test/extended/router/stress.go:

1. Polling timeout: 2 min → 5 min — the leader election lease lasts 1 minute; under heavy contention a replica may need 3+ lease cycles to update all routes.
2. Write-count bound: 50 → 75 — the async contention detector can lag behind update events, allowing extra writes before suppression kicks in.

This test caused 367 failures in a single 7-day window before the fix landed on main. The 4.20 nightly e2e-rosa-sts-ovn job continues to hit this flake (most recently with 52 writes vs the 50 limit).
