feat(falukant): update production counting logic and enhance localization

- Modified the production counting logic in FalukantService to count each completed production directly from the falukant_log.production table, simplifying the query structure.
- Added a new localization entry for "scoreHowToRaise" in Cebuano, German, English, Spanish, and French to provide users with clear guidance on how to improve their score through various factors.
- Updated the OverviewView component to display the new score improvement information, enhancing user experience and understanding of scoring dynamics.
