[fix][test] Extend SameAuthParamsLookupAutoClusterFailoverTest phase timeouts

[merlimat]

Motivation

SameAuthParamsLookupAutoClusterFailoverTest.testAutoClusterFailover drives three state-convergence phases — failover 0->2, recover 2->1, recover 1->0 — each bounded by Awaitility.await().atMost(60, SECONDS). The probe timeout inside SameAuthParamsLookupAutoClusterFailover is 3 seconds and recoverThreshold is 5, so a single slow or failing probe per iteration can stretch one phase close to 30 seconds. On slow CI agents the cumulative variance pushes the final phase past 60 seconds and the test fails with ConditionTimeoutException.

Modifications

• Raise each Awaitility.atMost from 60s to 120s so a single phase can still complete even when every check cycle is stretched by slow probes.
• Raise the overall test timeOut from 240s to 480s so the three per-phase budgets still fit comfortably along with setup and teardown.
• Add a comment explaining the sizing decision.
