Report button moves under the exercise, bottom-right

The red "!" left the top chrome (it read as chrome and was easy to
mis-tap) and now sits in a row under the exercise: the AI disclaimer stays
centred, the report control is right-aligned with the card edge and is a
44px target. Applies to study, Smart Review and exam sessions; the results
slides keep just the disclaimer.

phase-2 suite now asserts the placement (below the card, right-aligned,
not in the header, >=44px) — 60 checks.

README: decision 52 updated. SW -> freezmo-v43.
