Fix thread leak and graceful shutdown issue in NightConfigWatchThrottler 
Problem:
- FileSystemWatchService threads accumulate over time (observed 17+ threads)
- Threads cannot be interrupted during container shutdown due to unhandled parkNanos()
- Container fails to stop gracefully, requiring force kill

Root cause:
- LockSupport.parkNanos() called without interruption handling
- No shutdown detection mechanism
- Threads continue polling file system even when JVM is terminating

Changes:
1. Add AtomicBoolean shutdown flag to prevent new watch iterations during shutdown
2. Add proper thread interruption handling with graceful fallback to empty iterator
3. Register shutdown hook to set flag on JVM exit

Testing:
- Verified threads no longer accumulate after multiple config reloads
- Container now responds to SIGTERM and stops within 5 seconds
- CPU usage returns to normal after shutdown sequence
