feat: Integrate unified gRPC server for enhanced service management

- Added `UnifiedGRPCServer` class to host both ImGuiTestHarness and ROM service, allowing simultaneous access to GUI automation and ROM manipulation.
- Implemented necessary header and source files for the unified server, including initialization, start, and shutdown functionalities.
- Updated CMake configurations to include new source files and link required gRPC libraries for the unified server.
- Enhanced existing services with gRPC support, improving overall system capabilities and enabling real-time collaboration.
- Added integration tests for AI-controlled tile placement, validating command parsing and execution via gRPC.
