Fix material switch padding on item_device_form layout

[Divinelink]

Description

This pull request addresses the missing padding in the item_device_form.xml, which caused the Material Switch to appear too close to the edge of the screen. To resolve this, I added the same padding used by the other Material Switch components through their style.

Let me know if this works for you!

Thanks for contributing - it's on my radar (and looks good/unproblematic). Just other/unrelated (procedural) things going on at the moment, thus not merging right away.
