Keep QTI item content the editor doesn't write through an edit

[rtibblesbot]

Summary

• Edits keep stylesheets, modal feedback, extra outcomes, non-hint catalogs and root attributes (xsi:schemaLocation), in schema order.

References

Fixes #6290.

Reviewer guidance

Open questions:

• Modal feedback goes dormant once response processing is regenerated. Make such items read-only?
• <qti-template-processing> is still dropped; it can reset the edited correct answer. Keep it, or read-only?
• tool-name/tool-version carry over. Stamp Studio's own?

Manual QA — import "Skeletal Structure - Practice" (Kolibri QA Channel > Courses > Hummingbird Biology > Anatomy & Physiology > Skeletal Structure) into an editable channel:

1. Edit a question two times
   1. QUESTIONS tab, Edit question 1.
   2. Change one answer. CLOSE.
   3. Edit. Change a different answer. CLOSE.
   4. Edit. Each answer shows once, both changes kept, correct answer unchanged.
2. Change the correct answer
   1. Edit question 2. Mark as correct answer on another answer. CLOSE.
   2. FINISH, reopen. Selected answer is correct.
3. Create a new question
   1. NEW QUESTION. Question, two answers, one correct. CLOSE.
   2. Edit. Mark the other correct. CLOSE.
   3. Edit. New correct answer selected.

Look out for:

• QUESTIONS tab: a question shown twice or "Incomplete".

Styled/feedback items exist only in test content; see Evidence.
