Update: Allow per-question overrides for showing feedback, marking, and model answer (fixes #232)

[swashbuck]

Fixes #232

Update

• Add new opt-in property _assessment._questions._allowComponentOverrides (default false). When enabled, article-level values for _canShowFeedback, _canShowMarking, and _canShowModelAnswer are not pushed to question components - each component's own values apply. When disabled (default), legacy behavior is preserved - article-level values always overwrite component values.
• Update schemas and documentation
• Add migration scripts

Testing

A. Legacy behavior (default _allowComponentOverrides: false):

1. Set up an assessment article with one or more question components. On a component, set "_canShowModelAnswer": true in components.json.
2. In the article's _assessment._questions block, omit _canShowModelAnswer entirely.
3. Run the course, submit an incorrect answer to exhaust attempts.
4. Confirm the Show Correct Answer button does not appear (article-level default false overrides component, matching pre-fix behavior).

B. New opt-in behavior (_allowComponentOverrides: true):

5. In the same article, set "_allowComponentOverrides": true in _assessment._questions.
6. Run the course, exhaust attempts on the component with _canShowModelAnswer: true.
7. Confirm the Show Correct Answer button does appear.
8. With _allowComponentOverrides: true, set _canShowModelAnswer: false explicitly at the article level. Confirm the Show Correct Answer button still appears on the component with _canShowModelAnswer: true - article-level values do not override component values when the flag is enabled.

C. Authoring tool / schema:

9. Author a new assessment article in AAT. Confirm _allowComponentOverrides defaults to false and the article behaves identically to courses authored on the previous version.

D. Migration:

10. Run the migration against a course authored on v5.4.1 or earlier. Confirm every assessment article gains _assessment._questions._allowComponentOverrides: false.
