Migrate Enrollment API callers from v1 to v2 (FC-0118)

Summary

The Enrollment REST API on edx-platform has been standardized under FC-0118 (ADRs 0025–0040) and re-released as /api/enrollment/v2/. frontend-app-learning is one of four MFEs that currently call the v1 endpoints and needs to migrate.

The v1 endpoints remain live (no immediate breakage). The v2 endpoints add a standardized error envelope, OpenAPI 3.x schemas, and consistent auth (JwtAuthentication + SessionAuthenticationAllowInactiveUser, no BearerAuthentication/OAuth2Authentication).

Endpoints to migrate

Call sites (grepped 2026-07-03)

GET /api/enrollment/v1/enrollment — list caller's enrollments

• src/courseware/course/course-exit/data/api.js:32,35 — Course Exit / recommendations screen

POST /api/enrollment/v1/enrollment — enroll

• src/alerts/enrollment-alert/data/api.js:6,7 — Enrollment Alert banner on the outline (postCourseEnrollment)

Tests referencing the v1 URL (update alongside):

• src/course-home/outline-tab/OutlineTab.test.jsx

Notes on the response envelope

Errors now follow the ADR 0029 standardized format. Code that reads response.data.detail may need to read response.data.error.detail. Success payloads are unchanged.
