Add ipc/character.ipc.ts and ipc/location.ipc.ts for character and location database interactions

- Introduce IPC handlers in `ipc/character.ipc.ts` and `ipc/location.ipc.ts` for CRUD operations, attributes management, and related actions.
- Register character and location IPC modules in `main.ts` for global accessibility.
- Utilize `createHandler` pattern for consistent and modular IPC handler implementation.
- Enhance type definitions for character and location functionalities, improving code consistency.
