fix test: properly mock pod selector calls to resolve immediately

The withTimeout test was failing because:
1. The mock made ALL ApiProxy.request calls hang, but the implementation
   has 4 sequential requests (1 CRD + 3 pod selectors) each wrapped in
   their own withTimeout
2. Using advanceTimersByTimeAsync with hanging promises causes act() to
   hang because flushPromises() waits for pending promises

Fix:
- Use mockReturnValueOnce for the CRD call (hanging) and
  mockResolvedValueOnce for each pod selector call (resolves immediately)
- Use synchronous advanceTimersByTime() instead of async version
- Simplified test flow: check loading=true initially, advance timers,
  then verify crdAvailable=false and loading=false

Fixes PRI-1040
