Fix player dismiss gesture stuck after panel dismiss with comments expanded

Reset isCommentsExpanded and commentsFrame on the NavigationCoordinator
directly when the portrait panel is dismissed, since PortraitDetailsPanel
owns its own @State that doesn't sync back through .onChange during dismiss.
Also track comments overlay frame via GeometryReader so the dismiss gesture
can allow swipes outside the comments area instead of blanket-blocking.
