fix: portal registry schema validation failure (#1511)

Resolves #1511. Added missing expanded schema fields to 5 portals
(workshop, archive, chapel, courtyard, gate).

Added: portal_type, world_category, environment, access_mode,
readiness_state, telemetry_source, owner, destination.action_label.

test_portals_json_uses_expanded_registry_schema: PASS
