GitHub Actions 6564381492 test: increase test coverage to 86.1% and fix SSRF test failures 
- Add 16 comprehensive tests for user_handler.go covering PreviewInviteURL,
  getAppName, email normalization, permission/role defaults, and edge cases
- Add 14 unit tests for url.go functions (GetBaseURL, ConstructURL, NormalizeURL)
- Refactor URL connectivity tests to use mock HTTP transport pattern
- Fix 21 test failures caused by SSRF protection blocking localhost
- Maintain full SSRF security - no production code security changes
- Coverage increased from 66.67% to 86.1% (exceeds 85% target)
- All security scans pass with zero Critical/High vulnerabilities
- 38 SSRF protection tests verified passing

Technical details:
- Added optional http.RoundTripper parameter to TestURLConnectivity()
- Created mockTransport for test isolation without network calls
- Changed settings handler test to use public URL for validation
- Verified no regressions in existing test suite
