refactor(test): move test helper to proper location

Move generate-report-test-helpers.mts from src/ to test/helpers/:
- src/commands/scan/generate-report-test-helpers.mts → test/helpers/
- Update all imports in test files (3 files)
- Add export to test/helpers/index.mts
- Update documentation comment with new path

Test helpers belong in test/ directory, not src/. This follows
established pattern from test/helpers/README.md which documents
test utility organization.

All tests pass after relocation.
