Implement URI-based API versioning with /api/v1 prefix across all routes.
This establishes a foundation for future API evolution and breaking changes.
Changes:
- server.ts: All routes mounted under /api/v1/ (15 route handlers)
- apiClient.ts: Base URL updated to /api/v1
- swagger.ts: OpenAPI server URL changed to /api/v1
- Redirect middleware: Added backwards compatibility for /api/* → /api/v1/*
- Tests: Updated 72 test files with versioned path assertions
- ADR documentation: Marked Phase 1 as complete (Accepted status)
Test fixes:
- apiClient.test.ts: 27 tests updated for /api/v1 paths
- user.routes.ts: 36 log messages updated to reflect versioned paths
- swagger.test.ts: 1 test updated for new server URL
- All integration/E2E tests updated for versioned endpoints
All Phase 1 acceptance criteria met:
✓ Routes use /api/v1/ prefix
✓ Frontend requests /api/v1/
✓ OpenAPI docs reflect /api/v1/
✓ Backwards compatibility via redirect middleware
✓ Tests pass with versioned paths
