feat: Add enrollments actions endpoints

[brianjbuck-wgu]

Description

Adds two new v2 instructor API endpoints to support the Enrollments Actions tab in the Instructor Dashboard MFE.

These endpoints provide structured JSON responses for MFE consumption, replacing the unstructured string responses from the v1 GetStudentEnrollmentStatus endpoint and adding a new mode-change capability.

New Endpoints

1. GET /api/instructor/v2/courses/{course_id}/enrollment_status

Check the enrollment status of a learner. Resolves the learner's state as one of: active, inactive, pending (CourseEnrollmentAllowed exists), or never_enrolled.

{
    "course_id": "course-v1:edX+DemoX+Demo_Course",
    "enrollment_status": "active",
    "mode": "audit",
    "email_or_username": "learner@example.com",
    "message": "Enrollment status for learner@example.com: active"
}

• Permission: VIEW_ENROLLMENTS (course staff, instructors)
• Accepts email_or_username query parameter (email or username lookup)
• Handles non-existent users gracefully (returns never_enrolled)
• Checks CourseEnrollmentAllowed for pending invitations

2. POST /api/instructor/v2/courses/{course_id}/change_enrollment_mode

Change a learner's enrollment mode (e.g., audit → verified). Creates a ManualEnrollmentAudit record for traceability.

{
    "course_id": "course-v1:edX+DemoX+Demo_Course",
    "email_or_username": "learner@example.com",
    "old_mode": "audit",
    "new_mode": "verified",
    "message": "Enrollment mode changed from audit to verified for learner@example.com."
}

• Permission: CAN_ENROLL (course staff, instructors)
• Validates the target mode against CourseMode.modes_for_course_dict
• Returns 404 if user not found or not actively enrolled
• Returns 400 if target mode is invalid or same as current mode

Impacted Roles

• Course Staff / Instructors: New API endpoints for enrollment management actions
• Developers: New v2 API surface for MFE integration

   • Verify active for enrolled user, inactive for deactivated enrollment, pending for CEA-only user, never_enrolled for unknown user

2. Change enrollment mode:

   • As course staff, POST /api/instructor/v2/courses/{course_id}/change_enrollment_mode with {"email_or_username": "<learner>", "mode": "verified"}
   • Verify mode is changed and ManualEnrollmentAudit record is created
   • Verify 400 for invalid mode or same-mode request
   • Verify 404 for non-existent or inactive user

Deadline

None

do we really need to create a new endpoint for this GET /api/instructor/v2/courses/{course_id}/enrollment_status?
Im currently using courses/${courseId}/instructor/api/get_student_enrollment_status and i don't see any new attribute that is needed/mandatory for the new mocks 🤔

[diana-villalvazo-wgu]

I think is missing POST apis for enroll and unenroll learners, also to add/remove beta testers
