Refactor IPC handlers, types, and models for streamlined data handling

- Unified return types across IPC handlers (`Character`, `Location`, `World`, and `Book`) for consistency.
- Replaced `BookListProps` with `BookProps` for simplified type usage in components and handlers.
- Cleaned up obsolete `BookListProps` interface and applied consistent typings throughout.
- Updated imports to include revised response types (`CharacterListResponse`, `LocationListResponse`, `WorldListResponse`).
- Adjusted data transformation logic in `BookList` and related components to align with new type definitions.
