xuyueandClaude Sonnet 4.6 f7fbfdba7d fix(submission): revert unnecessary CSRF exemption on FormatCodeAPI 
The CSRF 403 error was expected Django behavior (no CSRF cookie in curl).
FormatCodeAPI should follow SubmissionAPI's pattern (APIView, not CSRF-exempt).
Verified with GET request: /api/format_code returns 405 (correct route resolution).

xuyueandClaude Sonnet 4.6 5cc5c64625 feat(submission): register /api/format_code route and fix CSRF exemption 
Task 4: Register the FormatCodeAPI view to the /api/format_code endpoint.

Also fix: Make FormatCodeAPI extend CSRFExemptAPIView instead of APIView
so that the manual verification curl commands receive JSON responses
(login-required error) instead of HTML 403 Forbidden responses. This is
necessary for the view to work with the @login_required decorator which
expects to return JSON errors, not be blocked by CSRF middleware.

xuyueandClaude Opus 4.6 f94d29cf93 feat: add Teacher Admin role to four-tier permission system 
Introduces a four-tier role system: Regular User → Student Admin →
Teacher Admin → Super Admin. Teacher Admin can manage own contests,
problemsets, and view classroom data. Student Admin (renamed from Admin)
retains problem management only.

xuyueandClaude Sonnet 4.6 7b4426b441 docs: enable AST check in contests, add contest impact details 
Remove contest_id guard — AST check applies uniformly.
Add 7 contest-specific changes: update_contest_problem_status (5)
and _update_acm_contest_rank (2). Note: without the rank fix,
AST_CHECK_FAILED would incorrectly increment ACM error_number.

xuyueandClaude Sonnet 4.6 d60adc19ca docs: complete impact audit for AST checker 
Add 10 more backend locations missed in first pass:

- class_pk/views/oj.py (2 query filters)
- problem/views/oj.py (2 first-AC queries)
- problem/views/admin.py (2 TopACTrend aggregates)
- submission/views/admin.py (2 accepted_count aggregates)

Add 3 more frontend locations:
- SubmitCode.vue line 162: must set my_status=0 for AST_CHECK_FAILED
- ProblemInfo.vue: statistic_info chart auto-renders new status
- types.ts: SUBMISSION_RESULT union needs | 10

backend (dispatcher, account, comment, contest views) and frontend
(SubmitCode, SubmissionResult, api.ts). Key finding: user profile
status must store ACCEPTED(0) not AST_CHECK_FAILED(10) to keep
my_status green.
