feat(i18n): add update flag strategy settings

Add new "updateFlags" section to settings navigation and implement update flag strategy configuration. The strategy allows users to choose when update badges appear:
- Match updates by base model (only show when new release shares same base model)
- Flag any available update (show whenever newer version exists)

Includes translations for English, German, Spanish, and French locales.
