refactor: implement P1 WorkManager hygiene optimizations

- Add WorkManagerHygiene.java: Optimized WorkManager best practices
  * Worker lifecycle management
  * Constraint optimization
  * Retry policy management
  * Resource cleanup
  * Performance monitoring

- Add OptimizedWorker.java: Base class for optimized workers
  * Proper lifecycle management
  * Resource cleanup
  * Performance monitoring
  * Error handling
  * Timeout management

- Add DailyNotificationFetchWorkerOptimized.java: Optimized fetch worker
  * Extends OptimizedWorker for hygiene best practices
  * Proper resource management
  * Timeout handling
  * Performance monitoring
  * Error recovery
  * Memory optimization

WorkManager Hygiene Improvements:
- Proper worker lifecycle management
- Optimized constraints based on network/battery conditions
- Intelligent retry policies with exponential backoff
- Resource cleanup and memory management
- Performance monitoring and metrics
- Timeout handling and cancellation support

P1 Priority 3: WorkManager hygiene - COMPLETE ✅
