Subject: [PATCH] Add comprehensive API security E2E tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Tests every /api/v1/ endpoint (86 endpoints × 4 auth levels = 316 tests):
- Unauthenticated requests → 401 on all endpoints
- User role → 403 on admin-only endpoints
- Viewer role → 403 on admin-only endpoints
- Admin role → allowed on all endpoints
- Cross-user isolation: users cannot access other users' profiles

Uses Bearer API tokens (created directly in DB) to avoid
Better Auth rate limiting during test execution.
