fix ontology capitalisation inconsiustency
Fixed some capitalisation inconsistency issues in the UNTP ontology and mapped the changes back to existing schema and samples (for now)
Ontology (untp-ontology.jsonld):
- untp:schemeID (on Classification) → renamed to untp:schemeId — now consistent with the existing untp:schemeId on RegisteredIdentity
- untp:trustmark (on Endorsement/ConformityScheme) → renamed to untp:trustMark — now consistent with the existing untp:trustMark on ConformityAttestation
Context (untp-context.jsonld):
- All 12 occurrences of "@id": "untp:schemeID" → "@id": "untp:schemeId"
- All 3 occurrences of "@id": "untp:trustmark" → "@id": "untp:trustMark"
- JSON key names ("schemeID", "trustmark", "trustMark") are preserved as-is, so schemas and samples continue to work — the context just maps them to the now-consistent ontology terms.
