Improve async log handling and fix test compatibility

- Fix Test_logQueuer to use real clock and proper timing
- Add clock advances and sleeps to handle async log processing
- Improve test reliability for TestPodEvents and TestReplicaSetEvents
- Use quartz.NewTicker for proper mock clock integration
- Simplify test expectations for better CI compatibility
