refactor(linkml): apply RiC-O slot naming conventions (Rule 39)

Rename slots to follow Records in Contexts (RiC-O) style naming: - Add 'has_' prefix for possession predicates (has_acquisition_method) - Add 'is_or_was_' prefix for temporal relationships - Add 'has_or_had_' for bidirectional temporal relations Key changes across 496 schema files: - acquisition_method → has_acquisition_method - acquisition_date → has_acquisition_date - acquisition_source → has_acquisition_source - access_policy_ref → has_access_policy_reference - arrangement → has_arrangement - parent_custodian → is_or_was_suborganization_of (hierarchy) - parent_custodian → associated_custodian (event association) Also adds new slots following RiC-O patterns: - is_or_was_aggregated_by - is_or_was_allocated_by - is_or_was_archive_department_of - was_approved_by, was_archived_at, was_asserted_by This aligns with AGENTS.md Rule 39: Slot Naming Convention (RiC-O Style) for accurate temporal semantics in heritage custodian ontology. Net change: +2,063 lines (new slots added, old patterns consolidated)
