✅ test(auth): update tests for minimal JWT claims architecture

- Update auth.controller.spec.ts to expect accessToken/refreshToken/expiresIn
- Refactor jwt-validation.spec.ts to test minimal claims (sub, email, role, sid)
- Remove B2B/B2C org and credit_balance claims from tests (fetched via API now)
- Add Better Auth CLI config for schema generation
