Refactor schema and slot definitions for heritage-related entities

- Added new slot `is_or_was_used_in` to `DataServiceEndpointType` for tracking usage in the heritage sector.
- Replaced `heritage_society_subtype` with `has_or_had_hyponym` in `HeritageSocietyType`.
- Updated `HistoricBuilding` to use `has_or_had_status` instead of `heritage_status`, linking to the new `HeritageStatus` class.
- Removed deprecated slots: `heritage_relevant_count`, `heritage_relevant_percentage`, `heritage_sector_usage`, `heritage_society_subtype`, and `heritage_status`.
- Introduced new classes `Connection`, `HeritageSector`, and `HeritageStatus` to better structure heritage-related data.
- Migrated relevant descriptions and annotations to align with new schema standards.
- Updated slot definitions to improve clarity and consistency across the schema.
