feat(desktop): v0.4.4 - WiFi configuration via serial port

## New Features
- WiFi Configuration Modal: Configure ESP32 WiFi credentials directly from the desktop app
- Serial port WiFi commands: Sends wifi_config/wifi/set ssid commands via serial
- Improved feedback UI with status indicators (Success/Commands Sent/Error)

## API Improvements
- New Tauri command: configure_esp32_wifi(port, ssid, password)
- 21 new integration tests covering all API functionality
- ESP32 VID/PID detection for CP210x, CH340, FTDI, and native USB

## UI Enhancements
- WiFi button in Serial Ports table for ESP32-compatible devices
- Modal with SSID/password inputs and clear status feedback
- "Done" button after configuration with "Try Again" option

## Testing
- 18 unit tests + 21 integration tests = 39 total tests passing
- Tests cover: discovery, settings, server, flash, OTA, provision, WASM, state, domain models
