Fix failed D4D extractions and ensure complete metadata coverage

- Regenerated fairhub_d4d.yaml and physionet_b2ai-voice_1.1_d4d.yaml that failed due to YAML syntax errors
- Added corresponding metadata files for both fixed extractions
- Created fix_failed_extractions.py script with improved YAML validation
- All D4D files now have complete metadata coverage (8/8 files with metadata)

Fixed files:
- AI_READI/fairhub_d4d.yaml + metadata
- VOICE/physionet_b2ai-voice_1.1_d4d.yaml + metadata
