Firmware build fixes: HardwareSerial for TMC2209, ArduinoJson 7.4, ESP-IDF 5.x WDT

Browse Source 
- TMC2209Stepper: use HardwareSerial& constructor (SoftwareSerial deleted on ESP32)
- ArduinoJson: replace deprecated containsKey() with doc["key"].is<T>()
- esp_task_wdt_init: use struct-based config API (ESP-IDF 5.x)
- ESPAsyncWebServer: fix library owner (mathieucarbou, not wifwaf)
