Add PlatformIO project setup, local libraries, and PCB Gerber files

- Add platformio.ini for ESP32 DevKit (Arduino framework, espressif32 6.10.0)
- Vendor ArduinoJson, MPU6050_tockn, SCServo, Simple_FOC, and WebSockets
  so a fresh clone builds without downloading dependencies
- Add .gitignore rules for PlatformIO/IDE build artifacts
- Add controller PCB Gerber and drill files
