f-1563 improve the display of questions in the manual grading interface

[morozov-av]

1. Convert multiple-choice indexes to option letters (0 → A, 1 → B)
2. Reconstruct and display Parsons block order
3. Display Matching and Drag-and-Drop answers as readable labeled pairs instead of raw JSON
4. Preserve saved interactive attempts and required Drag-and-Drop sizing metadata
5. Refactor questionTypes into colocated component folders with dedicated utilities, barrel exports, and tests

I'm not seeing anything different in this view:

I think when most instructors want to manually grade they use this. Many have requested this view where they select all questions and then just one student so they can see all of the students work for a single assignment.

Thanks. I’ve updated manually grad dialog

Great progress. Ideally the answer for the parsons problems would just look like the code in plain text as the student arranged it. that would work for other parsons questions as well as the coding problems.

@bnmnetp
Tests were failing due to changes introduced in c8b7298
Profile email test used a different async event loop, causing cascading asyncpg failures, and the email form field remained required despite the new blank-email scenario

Thanks, I run the tests locally with every build.... I must have missed something when I was merging that PR. I'm looking into it now.

@ascholerChemeketa -- this should still do what you wanted.
