Closes #51865 

The Tool Permissions and Edit Prediction Providers pages have settings
that do not conform very well to the usual setup, because of this they
are specially defined in .../settings_ui/src/pages . Due to this setup,
they do not benefit from the same automatic responsive setup as the
other parts of the settings ui. This was causing issues w/ narrow
windows, where fields and text were extending past the side of the
window or just not displaying.
All that was needed to fix it was some tweaks to the structure and css
of those pages, and its smooth sailing. Maybe in the future
`render_settings_item` can be made broader and support these use cases
as well so this doesn't have to be handled manually.
