fix(map): one close button on the spot sheet

SheetContent renders a built-in close X, and SpotBottomSheet adds its own in
the header row - so tapping a spot showed two. Added an opt-in hideClose prop
to SheetContent and used it on the spot sheet (which keeps its own, placed in
the header). Also padded the new mint sheet header clear of the built-in close.
