Fixes two instances of text being cut off on mobile

1. Fixes the "quick edit" text from being cut off on the general settings page

   • Checkbox doesn't respect word wrapping (bug report)
   • One workaround is to use contentItem with a Label as described here
   • because this particular checkbox is inside a ColumnLayout to make the label actually wrap I had to use Layout.preferredWidth as described here

2. Was going to apply the same fix to the appearance -> "text on the right" option (which barely cut off the end of "right" but after setting the form layout to respect the parent width then everything shifts slightly (correctly imo) and makes room.

   • Any of these could run into the problem if the string is longer unless the fix done for the first issue (using contentItem) but since this fixed the immediate issue on PinePhone and Android this seemed like the safer first step
