test(email, verification, login): 更新测试中的断言内容, 修复测试error.

- Replace boolean assertions with structured result object checks in email service tests
- Update email service tests to verify success flag and isTestMode property
- Add error message assertions for failed email sending scenarios
- Change logger spy from 'log' to 'warn' for test mode email output
- Update test message to clarify emails are not actually sent in test mode
- Add code and createdAt properties to verification code stats mock data
- Fix TTL mock value from -1 to -2 to correctly represent non-existent keys
- Replace Inject decorator with direct UsersService type injection in LoginCoreService
- Ensure verification service tests properly mock TTL values during code verification
- Improve test coverage by validating complete response structures instead of simple booleans
