refactor: create separate BLoCs for each screen with comprehensive tests
- Created 8 separate BLoCs (Home, Library, BookDetails, AddBook, Scanner, Categories, Wishlist, Settings) - Each BLoC has its own event, state, and bloc files - Added 70 comprehensive tests covering all BLoC functionality - All tests passing (70/70) - Fixed linting issues and updated deprecated APIs - Improved code organization and maintainability
