• GET /api/educator/logs/:lessonPlanId: Returns assignment/edit history for a lesson plan, with editor populated for display.
• POST /api/educator/assign-atoms: Maps to the atom-based assignment handler in educatorController (activities → atom task templates, enrolled students, prerequisite checks, EducationTask + Progress updates inside a MongoDB session/transaction). Request body uses snake_case fields such as lesson_plan_id, assignment_date, deadline_offset_days.
