fix(chapters): keep landscape when opening chapter list on iOS

The chapter list <Modal> had no `supportedOrientations`, so iOS (which
defaults modals to portrait-only) rotated the app back to portrait when
the list was opened from the landscape player. Allow portrait + landscape
so the sheet opens in the current orientation. Android ignores the prop.
