refactor: replace Phase 2 label matching with PDF text-stream caption pairing
- Extract captions from PDF text dict instead of DocLayout caption boxes
- Use _CaptionBlock dataclass to carry authoritative ID, kind, text, bbox
- Pair captions to content boxes with directional preference (figure below, table above)
- Filter out uncaptioned boxes (Algorithm pseudo-code, unnumbered appendix tables, false positives)
- Remove label_images_by_summary and Phase 2 rename pipeline entirely
- Update tests to cover text-based caption pairing and filtering
