feat(falukant): add character visual representation and settings

- Introduced FalukantCharacterVisual component to display character portraits and 3D figures based on user settings.
- Updated DirectorInfo, ChurchView, PoliticsView, and other components to utilize the new character visual component.
- Added visual settings management for users, allowing selection between portrait styles and display modes (portraits, 3D, or both).
- Implemented age rules for engagement and marriage in the backend, ensuring compliance with specified age limits.
- Created a new settings view for Falukant to manage visual preferences.
- Added new images for medieval character portraits.
- Updated translations for new settings and features in multiple languages.
