Enhance production certificate logic and event handling: Updated the daily recalculation process in FalukantFamilyWorker to decouple it from family migration, ensuring consistent execution. Introduced a new mechanism to reset certificates upon succession without heirs, improving user experience. Refined SQL queries for better data retrieval and event publishing, including distinct character selection logic. Enhanced documentation for clarity on the updated processes and their implications.
