fix(android): a field should look recessed, a button raised

They carried the same fill and the same pill, so the password field looked like a command. A field now holds 10 per cent white against a button's 18 and a main action's 30 - hollow against raised, which is the only cue left once borders are gone.

The settings panel also reclaimed the top of the screen, above the title: created hidden, FMX moves it to the head of the stack when it becomes visible. Its position is now reasserted each time it appears.
