docs(droid-control): note configurable transitions + code annotations

Reflect the post-processing additions shipped in factory-plugins#23:
- Bump component count from 22 to 23 (net +1: added CodeAnnotationOverlay
  and ShowcaseTransition; removed orphaned MotionBlurTransition).
- Replace 'Motion blur title-to-content transition' with the configurable
  list (motion blur is still the default).
- Add 'Syntax-highlighted code annotations for source-change overlays' to
  the compose-time effect list.
