Open queue sheet from tvOS player controls

Turn the tvOS bottom-row queue count indicator into a focusable button
that opens QueueManagementSheet in a fullScreenCover with an
ultraThinMaterial backdrop, matching the Settings sheet pattern. Hide
the sheet's close toolbar button on tvOS (Menu button dismisses) and
replace the unusable Menu-based queue mode picker with an icon-only
tap-to-cycle button.
