A few notes for consideration

[christianbeeznest]

2e1b272 Adds Progressive adaptive exercise mode behind exercise.quiz_question_category_destinations.

Includes:

• V210 migration for c_quiz_rel_category.destinations and c_quiz_destination_result.
• Doctrine entity for adaptive destination results.
• Exercise settings schema registration.
• Exercise configuration support and category destination UI.
• Runtime navigation by category score thresholds.
• Result display for achieved adaptive level.

There's a conflict in the language file (apparently terms sorted in a different order and indentation). Not sure where that comes from, so I'm not trying to fix it yet.

• On /resources/exercise/537/create, the "Feedback" section in 1.11 has 4 options. I only see 3 here (At end of test, Exam, Adaptative test with immediate feedback)
• the "Enable start time"/"Enable end time" options open a calendar
• The "Extra settings" & "Metadata" spaces that appear at the bottom of the creation form are confusing (choosing a language next to "Hide attempts table on start page" which is not related, then a "Metadata" section to choose an "Advanced courses list" !? There's some text missing, it seems.
• As an admin, when I create an exe with 2 questions and I want to preview it, there's no submit button!
• In a test with multiple questions on one page, there should be a "Save" button under each question (currently only at the end of the page)
