[rp2040] Update arduino-pico framework from 3.9.4 to 5.5.0

Update the RP2040 Arduino-Pico framework to 5.5.0 (from 3.9.4) and
the platform to v1.4.0-gcc14-arduinopico460 (GCC 14 toolchain).

Breaking changes adapted:
- pico-sdk 2.0: padsbank0_hw renamed to pads_bank0_hw
- Arduino.h now defines NOPIN as a global macro (SerialPIO::NOPIN removed)
- WiFi: cyw43_tcpip_link_status() no longer works because the Arduino
  framework's __wrap_cyw43_cb_tcpip_init is a no-op (the SDK's internal
  netif is never initialized). Switched to cyw43_wifi_link_status() for
  radio state + WiFi.status()/WiFi.connected() for IP-level state.
- WiFi: Use beginNoBlock() instead of begin() to avoid 20s+ blocking
- WiFi: Use WiFi.disconnect() for proper lwIP/DHCP cleanup
