Add IPCManager for UNIX domain socket communication:

- Introduced `IPCManager` class to handle IPC using UNIX domain sockets.
- Updated `MediaManagerApplication` to initialize and manage `IPCManager` during startup and shutdown.
- Enhanced logging for IPC initialization and cleanup.
- Updated `config.properties.example` with `ipc.socket.path` property.
