feat(falukant): implement score threshold logic and enhance UI feedback for certificate progression

- Added a new function to calculate score thresholds based on certificate levels, improving the logic for determining promotion eligibility.
- Updated the FalukantService to include new properties for score and requirement checks, enhancing the decision-making process for certificate readiness.
- Enhanced the OverviewView component to display detailed hints and states regarding certificate progression, providing users with clearer feedback on their status.
- Localized new strings in multiple languages to support the updated UI elements and hints, improving user experience across different languages.
