## Summary * Implements #380, allowing the user to see the device's MAC address in order to register on wifi networks ## Additional Context * Although @markatlnk suggested showing on the settings screen, I implemented display at the bottom of the WiFi Networks selection screen (accessed via "File Transfer" > "Join a Network") since I think it makes more sense there. * Tested on my own device  --- ### AI Usage While CrossPoint doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it helps set the right context for reviewers. Did you use AI tools to help write this code? _**YES**_ --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com>
