Move distractor explanations inline instead of a repeated bottom section

The "WHY OTHER OPTIONS ARE INCORRECT" aggregate section duplicated
explanations that selected wrong choices already showed inside their
own resolved follow-up quiz. Removed that section entirely; choices
the user never picked now get their "why incorrect" explanation
docked directly inside their own card (reusing the same followup
panel/attached-card styling), so every distractor's explanation lives
with its choice instead of in a separate list at the bottom.
