Add new classes and slots for enhanced data modeling

- Introduced VerificationStatus, Verifier, VersionNumber, ViabilityStatus, VideoCategoryIdentifier, VideoIdentifier, WhatsAppProfile, WordCount, WorkRevision, and WorldCatIdentifier classes to capture various aspects of data verification, categorization, and identification.
- Created corresponding slots such as analyzes_or_analyzed, unit_type, years_restricted, benefits_provided, consumes_or_consumed, has_or_had_contact_details, has_or_had_investment, has_or_had_liability, has_or_had_likelihood_score, has_or_had_location, has_or_had_net_asset, is_or_was_affiliated_with, is_or_was_allocated_to, is_or_was_alternative_form_of, is_or_was_categorized_as, is_or_was_used_by, and was_last_updated_at to facilitate detailed tracking and categorization of entities and their attributes.
- Each class and slot includes detailed descriptions, usage examples, and mappings to relevant ontologies to ensure interoperability and clarity in data representation.
