Rubric Grading: context UI improvements and minor fixes

[adi-herwana-nus]

Migration contains database changes for adding ratings to AI generated replies (coming in next PR).

Pull request overview

This PR improves the rubric grading playground and grading-context UX by introducing dedicated mock-answer management (including renameable mock answers), adding a read-only “view answer” flow that resolves grading contexts against a submission, and fixing/covering grading-context duplication semantics when duplicating questions. It also adds a migration + schema changes for rubric answer-evaluation feedback ratings and updates related translations/UI polish.

Changes:

• Add renameable, editable mock answers with full CRUD support (API, controller, serializers, reducer/types) and new playground prompts for create/edit + view-answer.
• Add an endpoint + client wiring to fetch grading contexts resolved for a specific real answer’s submission.
• Fix grading-context duplication behavior for rubric-gradable questions and expand specs/docs/migration/schema for related rubric grading enhancements.
