fix(client/settings): one marker per override, footers at footer size, air under Reset

The resolution marker hung off the Match-window toggle, which read as if that toggle
alone were overridden. Match-window, width and height are ONE override — they reset
together — so the marker belongs to the group, under the size control that ends it,
not to the first of the two rows that write it.

The new section footers inherited the app's 17pt body font, so the profile picker's
description sat visibly larger than every other description in Settings. Same style
as the footers that were already there.

And the marker carries a bordered button, which needs more air under the control
above it than a line of text does — most visible under the segmented refresh picker.
Added inside the marker, so every row that shows it is spaced alike.
