Sidebars take up entire screen on mobile; might be usable otherwise

[zmc]

I wanted to use the range test module, but I only have ESP32 devices and the docs say to not use the CSV-saving feature with the mobile apps. I tried connecting to meshtastic.local with my phone, and the web UI does indeed load, but as you see in the screenshot the sidebars effectively take up the entire screen, rendering most features inaccessible.

If the sidebars could by collapsed with a button, it seems it would work well as an alternative to the mobile apps.

Edit: Firefox 126.0, macOS 14

The webui is a desktop experience right now, mobile browser support for BLE and serial is really limited.
