fix(player): keep controls visible while settings popover is open

Re-enabling the auto-hide timeout (previous commit) let it fire while the
player settings popover was open, dismissing it mid-interaction — most
visibly on iOS, where the popover lives inside the controls and closes
when they fade out.

Surface the popover's open state up through DropdownView -> HeaderControls
-> Controls and pass it as useControlsTimeout's `disabled` flag, so the
auto-hide pauses while the menu is open and re-arms once it closes. iOS
reports open/close via the SwiftUI Popover binding; Android's menu is a
separate global bottom-sheet modal and is unaffected by controls hiding.
