refactor: Update ROM service implementation and CMake configurations

- Adjusted paths in CMake files to reference the correct location of `rom_service.proto`.
- Refactored `RomServiceImpl` to use a namespace alias for improved readability and maintainability.
- Updated method parameters in `RomServiceImpl` to utilize the new namespace alias for consistency.
- Added a new `rom_service.proto` file to define the ROM manipulation service, enabling remote operations for reading and writing ROM data.
- Enhanced the `RecentFilesManager` to utilize a utility function for retrieving the configuration directory, improving code clarity.
- Included necessary updates in CMake configurations to integrate the new proto file and ensure proper build setup.
