Add AP+STA WiFi manager and stabilize balancing
- Replace wifi.cpp/wifi.h with wifi_manager.cpp/wifi_manager.h: AP and STA run together, external WiFi credentials are stored in NVS and editable at /wifi, with optional static IP, 15s auto-reconnect, disconnect reason reporting, and build/version diagnostics - Fix MPU6050 I2C port to I2C0 to match the board wiring - Initialize distance_zeropoint at startup and on Robot Go! rising edge - Clamp angle_zeropoint to +/-10 degrees to prevent balance-point drift - Add DEBUG_DISABLE_YAW switch and periodic balance debug output - Update WiFi setup instructions in README.md and README_CN.md
