chore: enhance project configuration and improve service methods

- Added new commands to package.json for biome checks and unsafe writes.
- Updated tsconfig.json for better type checking and module resolution.
- Refactored service classes (AnimeService, CharacterService, MangaService, MediaListService, StaffService) for improved readability and consistency in method definitions.
- Enhanced test cases for anime and manga APIs to ensure comprehensive coverage and validation of responses.
