Downloading file from WebConfig causes reboot

[nseidle]

Original report.

I can't download the SD card files from the Wi-Fi config. It reboots and returns to Rover. Not always

Using a Postcard in Web Config mode, I attempted to download a 2.5MB file from the SD card and it reset:

Looks like a semaphore issue, aka, two things are trying to write to the card.

Why are we logging in Web Config mode?

According to the comments, handleFileManager() doesn't handle semaphore transactions, so we'll block at handleGnssDataTask().
