feat(android,ios): double-tap to seek, controls that fit upright, and a player TalkBack can use

- Double-tap the left or right third of the picture to seek ten seconds,
  with a mark showing the seek happened; the middle plays or pauses.
- A wide picture turns the phone's player to landscape by itself, once
  per episode, until the viewer uses the rotation button.
- Upright, the pickers past subtitles go behind a More menu instead of
  running off the edge. Controls are 48dp on Android and 44pt on iOS.
- With TalkBack or VoiceOver on, the controls stay up: a control that
  fades four seconds after it is reached cannot be found again. The tap
  layer is announced as Show or Hide controls.
