Fix the clipped answer field + the doubled AI note; ordering only where it fits

UI bug from a phone screenshot (short answer, Czech):
- The textarea was flex-shrunk inside the slide's column (58px instead of
  ~82px), clipping the typed answer mid-line. Every direct child of a
  study/review/guide slide is now shrink-0 and the slide scrolls instead.
- Two AI disclaimers were visible at once: the activity's own after the
  grading box plus the feed's row. The activity-level copy is gone; the
  feed/guide row (which also carries the report control) is the single one.
  The phase-2 check now asserts the note sits below the graded feedback.
- The mobile suite's backdrop-tap check is deterministic too (the spring
  animation made the measured box mid-flight).

Ordering activities: the deck prompt now allows them only when the notes
hold a real sequence (chronological events, process stages, procedure steps,
a lifecycle, a ranked scale) and points at matching / multiple choice /
true-false when they do not - "sort these" was landing on decks with no
order at all.
