fix : Passthrough logic inside hardReset()

[mikeysklar]

A small change to read the Passthrough checkbox state directly inside of hardReset(). This is to avoid issuing a reset on passthrough boards (M4 + ESP coprocessor).

This was tested locally, but I believe by forcing a read of the passthrough checkbox the web hosted code will also work.

Hardware successfully tested with this update:

Feather V2
PyPortal

Low risk level of making things worse. The Webserial_ESPTool has not worked in passthrough mode since August 2024.

Thanks! Let's merge and try this.

I did a shift-reload on the deployed page, but I'm still getting:

ESP Web Flasher loaded.
Connecting...
Connected successfully.
Try hard reset.
[Object.debug:196] Finished read loop
Error: Couldn't sync to ESP. Try resetting.
