refactor: extract OCR retry selection review reporting

[tryskian]

Summary

• extract OCR retry selection review schema, allowed actions, item builder, report builder, and formatter into tools/manual_eval_ocr_retry_selection_review.py
• keep tools/manual_evals_db_health.py exporting the same selection-review builder/formatter names for CLI and tests
• keep downstream selection template/validation/apply code using the shared allowed-actions contract from the extracted module
