fix: correct hallucinated PREMIS terms and Schema.org namespace mismatch
PREMIS ontology fixes (8 schema files):
- Replace invalid premis:hasRepresentation with dcterms:hasFormat
- Replace invalid premis:hasAccessRestriction with odrl:hasPolicy
- Replace invalid premis:hasPreservationPolicy with dcterms:conformsTo
- Replace invalid premis:hasAccessPolicy with dcterms:accessRights
- Replace invalid premis:hasStoragePolicy with dcterms:conformsTo
- Replace invalid premis:ProcessingStatus with skos:Concept
- Add proper close_mappings to valid PREMIS classes (premis:Representation, etc.)
- Document hallucinated terms in Rule 51 (AGENTS.md) for future prevention

Schema.org namespace fixes (3 frontend files):
- Update OntologyTermPopup.tsx: add normalizeSchemaOrgUri() function
- Update ontology-loader.ts: change schema prefix to https://schema.org/
- Update linkml-schema-service.ts: change schema prefix to https://schema.org/
- The schemaorg.owl file uses https:// but code was using http://

These changes ensure ontology term lookups work correctly for Schema.org
terms and that LinkML schema files only reference valid ontology predicates.

description: "Archive preserving materials for future use but with NO CURRENT ACCESS.\n\n**Wikidata**: Q112796578 (Dark\
\ Archive)\n\n**DEFINITION**:\n\nDark Archive is a preservation repository where materials are stored with \nNO ACCESS\
\ provided to users. The primary purpose is long-term preservation\nrather than current use. Access may be triggered\
\ by specific future events.\n\n**ACCESS SPECTRUM** (Light/Dim/Dark classification):\n\n| Type | Access Level | Purpose\
\ |\n|------|--------------|---------|\n| Light Archive (Q112815447) | Broadly accessible | Discovery & use |\n| Dim\
\ Archive (Q112796779) | Limited access | Selective access |\n| **Dark Archive** | No current access | Preservation\
\ only |\n\n**COMMON USE CASES**:\n\n1. **Digital Preservation**\n - Trusted Digital Repositories (TDR)\n - Backup/disaster\
\ recovery copies\n - Integrity verification archives\n\n2. **Rights-Restricted Content**\n - Orphan works awaiting\
\ rights clearance\n - Embargoed materials\n - Donor restrictions (sealed for X years)\n\n3. **Sensitive Materials**\n\
\ - Security-classified records\n - Privacy-protected personal data\n - Legally sealed court records\n\n4. **Format\
\ Migration**\n - Source materials preserved after migration\n - Original files kept for verification\n\n**TRIGGER\
\ EVENTS** (when dark becomes accessible):\n- Expiration of embargo period\n- Rights clearance obtained\n- Donor permission\
\ granted\n- Declassification decision\n- Original system failure (disaster recovery)\n\n**MULTILINGUAL LABELS**:\n\
- Dark Archive (de) [uses English term]\n\n**RELATED TYPES**:\n- LightArchive (Q112815447) - broadly accessible\n- DimArchive\
\ (Q112796779) - limited access\n- ClosedSpace - physical restricted access areas\n\n**ONTOLOGICAL ALIGNMENT**:\n- **SKOS**:\
\ skos:Concept (type classification)\n- **PREMIS**: premis:RightsStatus for access restrictions\n- **RiC-O**: rico:RecordSet\
\ with access restrictions\n- **Wikidata**: Q112796578\n\n**PREMIS INTEGRATION**:\n\nDark archives typically use PREMIS\
\ for preservation metadata:\n- `premis:RightsStatus` to document access restrictions\n- `premis:endDate` for embargo expiration dates\n\
- `premis:Agent` to identify the responsible custodian\n"

comments:
- Dark archives preserve materials with NO current access
- Access may be triggered by future events (embargo end, rights clearance)
- Common for digital preservation, disaster recovery, rights-pending content
- Part of Light/Dim/Dark access spectrum classification
- PREMIS metadata used for preservation and rights documentation
