Complete favorites system version separation and homepage update

- **ChapterSelector**: Added version filtering for chapter favorites
- **VersionProp**: ChapterSelector now receives and uses version parameter
- **API calls**: Chapter favorites include version in create requests
- **Favorites filtering**: .filter(...&& fav.version === version) for both level and chapter favorites
- **Homepage text**: Changed 'Both translations' to 'All translations' for future-proofing
- **All favorite types**: Now properly separated by Bible version

Users can now safely favorite books/chapters/verses in different versions without cross-contamination.
