feat(audio): add socket buffer configuration and monitoring

Add socket buffer configuration support with metrics collection for audio IPC connections. This improves performance monitoring and allows tuning socket buffers for optimal audio streaming performance.

- Introduce SocketBufferConfig struct with default and high-load presets
- Add socket buffer configuration to AudioServer and AudioInputServer
- Implement socket buffer metrics collection (size, utilization, overflow)
- Add new Prometheus metrics for socket buffer monitoring

-- **First-Class Audio Support** - JetKVM now supports in-process, low-latency audio streaming using ALSA and Opus, fully integrated via CGO. No external audio binaries or IPC required—audio is delivered directly from the device to your browser.
+- **First-Class Audio Support** - JetKVM now supports bidirectional, low-latency audio streaming using a dual-subprocess architecture with ALSA and Opus integration via CGO. Features both audio output (PC→Browser) and audio input (Browser→PC) with dedicated subprocesses for optimal performance and isolation.
 - **Free & Optional Remote Access** - Remote management via JetKVM Cloud using WebRTC.
 - **Open-source software** - Written in Golang (with CGO for audio) on Linux. Easily customizable through SSH access to the JetKVM device.
