Refactor VideoPost and WebObservation schemas; remove deprecated slots and migrate to new structures

- Updated VideoPost.yaml to include new slots and remove deprecated ones, enhancing video-specific properties.
- Removed extraction_confidence from WebObservation.yaml, streamlining the schema.
- Deleted obsolete slot files: characteristics.yaml, class_definition.yaml, confidence.yaml, confidence_method.yaml, confidence_score.yaml, confidence_value.yaml, count.yaml, and hosts_branch.yaml.
- Introduced ghost_slots.txt to track unused slots.
- Archived previous versions of characteristics, class_definition, confidence, confidence_method, confidence_score, confidence_value, count, and hosts_branch slots for historical reference.
- Added new slots: has_or_had_citation, has_or_had_city_code, and is_or_was_location_of with appropriate descriptions and mappings.
