Enhance production certificate logic and SQL queries: Updated the QUERY_UPDATE_FALUKANT_USER_CERTIFICATE to include certificate_productions_count_since for tracking production counts since the last level change. Modified the QUERY_GET_PRODUCTION_CERTIFICATE_INPUT_ROWS to filter completed productions based on this timestamp. Improved documentation for clarity on the new logic and its implications for user progression and data retention.
