test(auth): add comprehensive JWT authentication test suite

Add 17 tests in tests/test_auth.py covering all auth flows:
- Registration: first user admin, subsequent user, duplicate email
- Login: valid credentials, invalid credentials
- Protected routes: valid token, missing token, expired token, wrong token type
- Token refresh: valid refresh, invalid refresh, access-as-refresh rejected
- Admin endpoints: list users, change role, own-role prevention, permission checks

All tests use mocked database (no live DB required).

Closes leeworks-agents/SPARC#10
