Make input_* uneditable in UI

I use this:

You can restrict a whole card or just selected rows.

I have most of my restrictions set up to use a PIN, or check a “lock override” input boolean (that is also protected with a PIN). For quick adjustments I use the card/row PIN and they auto lock again after a short time but if I’m doing something more extensive I use the override switch that keeps them unlocked until I turn it off.
