feat(edint-censo-locales): add 5 candidate models for the commercial census

[albertoabellagarcia]

Summary

Translates the EDINT Commercial Premises Census Ontology (v0.1.0) from
https://github.com/EDINT-Ontologia/edint-ontologia-censo-locales —
commercial spaces, the entities operating in them, their permits,
terraces, and commercial aggregations (shopping centers, markets).

Five entities: CommercialAggregation, CommercialSpace, CommercialEntity,
Permit, Terrace.

Documented, not silently resolved

• The source redeclares Facility/InfrastructureElement/UrbanElement
  under its own namespace (byte-identical comments to
  edint-infraestructura's real classes) — treated as a copy-paste
  artifact, not materialized; subclass relationships target
  edint-infraestructura's real Facility instead, confirmed by the
  source's own example data using properties that only exist there.
• A new kind of type collision: this ontology's Permit (commercial
  activity licenses) and edint-censo-vehiculos's Permit (vehicle
  permits) are genuinely unrelated concepts that happen to share a class
  name — unlike prior collisions (thin stub vs. fuller real definition of
  the same concept).
• Two naming mismatches between the ontology's formal declarations and its
  own real example data (numberOfPermitedTables/Chairs vs. Spanish
  equivalents used in the example; TerracePeriod enum values).
• hasAccessType is used in real example data despite having no formal
  property declaration in ontology.ttl — included per real usage.

Testing

All 5 models' schema/context/example files parse and validate;
example.json validates against schema.json; standard-metadata.yaml parses;
index regenerated. All 5 examples grounded in a real Madrid market scenario
from the source's own examples/ directory.
