Merged PR 2049: feat(oms): add auto-refresh for open reward tasks

feat(oms): add auto-refresh for open reward tasks

Implements 5-minute polling to automatically update open reward tasks
without requiring manual page refresh. Uses reference counting to safely
handle multiple consumers starting/stopping the refresh.

Changes:
- Add startAutoRefresh/stopAutoRefresh methods with ref counting
- Add lifecycle hooks to carousel component for proper cleanup
- Add logging for debugging auto-refresh behavior
- Add refresh interval constant (5 minutes)

Closes #5463
