test: add comprehensive test coverage and improve code quality
- Add new test files for auth, service, and handler modules - Improve test organization and coverage - Refactor code for better maintainability - Add captcha, settings, stats, and theme handler tests - Add auth module tests (CAS, OAuth, password, SSO, state) - Add service layer tests for auth, export, permissions, roles - All Go tests pass (exit code 0) - All frontend tests pass (325 tests in 59 files)
