Refactor delete handling and improve logging in event processing

- Updated the HandleDelete function to allow delete events to be stored even if no valid targets are found, enhancing flexibility in event management.
- Improved logging to provide clearer insights when no deletions are processed, ensuring that issues are logged without blocking event acceptance.
- Refactored SHA256 validation tests and adjusted expected values to ensure accuracy in hash comparisons.
- Enhanced various test cases to improve coverage and reliability across the application.
