make replacement not delete, and filter query results respect limits

- Added detailed logging in GetSerialsByRange, CheckForDeleted, and SaveEvent functions to improve traceability during event processing.
- Implemented safety limits in GetSerialsByRange to prevent infinite loops during debugging.
- Updated event deletion logic to ensure only specific events are marked as deleted, improving clarity in event management.
- Refactored WouldReplaceEvent to maintain compatibility while simplifying the return values.
- Adjusted test cases to verify the correct behavior of replaced events and their deletion status.
