fix(quizzes): abandon stale in-progress attempts and harden time-limit checks
Problem ------- In-progress attempts that had exceeded the time limit were being resumed instead of flagged as stale. The submit flow also lacked server-side elapsed-time calculation, making it possible to bypass time constraints via client-side manipulation. Changes ------- Start-attempt flow - Detects expired in-progress attempts on session start - Marks stale attempts as abandoned - Creates a fresh attempt instead of resuming the expired one Submit flow - Computes elapsed time via DB TIMESTAMPDIFF (falls back to JS if unavailable) - Applies the same grace-window threshold used at start time - Marks expired attempts abandoned before throwing a timeout error - Uses server-computed elapsed time for timeTakenMinutes Shared helpers (new) - isAttemptExpired() — unified expiry check - calcElapsedTime() — DB-first elapsed-time calculation - abandonAttempt() — single-responsibility abandon transition4d96dfd

feat(enrollments): add endpoint for live student enrollment count
Add GET /api/enrollments/section/:sectionId/students/count to return the actual enrolled student count without fetching all records. ## Problem - current_enrollment counter in course_sections can become stale - Mobile app had to fetch all student records just to get a count - Stats cards showed incorrect counts vs actual enrolled students ## Solution - New endpoint using COUNT() query returning { count: number } - Reuses existing access control (assertStaffCanAccessSection) - Placed before /students route to avoid route conflicts ## Files Changed - enrollments.controller.ts: add getSectionStudentsCount endpoint - enrollments.service.ts: add getSectionStudentsCount method419018d

fix(assignments): change delete instruction endpoint to accept driveId instead of DB PK
The GET /api/assignments/:id response returns instructionFiles with driveId (Google Drive file ID) but no database PK, making the previous delete endpoint unreachable from the frontend. - Change route param from :instructionFileId (number) to :driveId (string) - Update service to lookup files by driveId instead of driveFileId - Update response field from deletedFileId to deletedFileDriveId Frontend can now use the driveId already available from the GET response with no frontend changes required.0717182
