feat(reels): collapsing icons hides the 3-dot menu too; add auto-scroll + playback speed

- 3-dot menu button previously rendered unconditionally alongside the
  collapse-toggle ("مثل اندروید" per the old comment, mirroring RN's
  pre-fix behavior) — now hidden when collapsed, matching RN's fix.
- Extended ExploreReelsUiContext with autoScrollEnabled (default off) and
  playbackSpeed (0.5x/1x/1.5x/2x), exposed via new rows in the options menu.
