feat(picow): wire a visible LED to GP2 in the relay example 

Confirmed the RP2040 GPIO -> PinManager -> wokwi-led path is fully wired
(identical to the AVR path): a wokwi-led wired anode->GP2, cathode->GND
lights when MicroPython drives GP2 HIGH. The board's componentId is its
boardType ('pi-pico-w') since loadExample's addBoard gives the first
board of a kind id == kind.

Add a red LED on GP2 to picow-wifi-relay-web-server and flip the relay
logic to active-high (ON => GP2 HIGH => LED lit) so the toggle is visible
on the canvas, not just in the device panel.
