Refactor IPC handlers to enforce consistent return types and enhance type definitions

- Update return types for IPC handlers in `character.ipc.ts`, `chapter.ipc.ts`, and `location.ipc.ts` for stricter type safety.
- Introduce new type definitions for better structure and clarity.
- Remove redundant console logs and unnecessary comments for cleaner code.
