Add SwarmUI settings management and portrait generation enhancements

- Introduced new API endpoints for managing SwarmUI settings, including fetching and saving presets and age rules.
- Updated the portrait generation logic to utilize the new settings structure, allowing for dynamic preset selection based on age.
- Enhanced UI components to support SwarmUI settings, including localization for new strings and improved styling for settings sections.
- Added tests to verify the functionality of new settings endpoints and portrait generation behavior.

This commit lays the groundwork for more flexible and user-friendly portrait generation options.
