Root cause: CheckBox/Button reserves vertical space for a text
baseline even with an empty string, so no amount of custom_minimum_size
or stylebox content-margin tweaking produced a true square - it just
came out close-but-not-quite in some layouts and visibly elongated in
others.
Decoupled the visual square from the CheckBox entirely: a plain Panel
(exactly 20x20, toggled by direct click) now draws the border/fill,
while a real (invisible) CheckBox still holds .button_pressed for the
rest of the code to read. Also added left padding on the row and
vertically centered both the square and the consent text within it.
Verified with a direct size dump (20x20 in both checked/unchecked
states, where it previously measured non-square) and rendered
screenshots of both states.
