feat(user): add certificate production tracking and update localization

- Introduced a new field `certificateProductionsCountSince` in the `FalukantUser` model to track the date from which production logs are counted for certificate requirements.
- Updated the `FalukantService` to utilize the new field for calculating completed productions since the specified date.
- Enhanced the UI to display the count of productions since the last promotion, with corresponding translations added for multiple languages including Cebuano, German, English, Spanish, and French.
- Implemented a method to delete old production logs, ensuring efficient data management while maintaining necessary historical records for certificate calculations.
