fix: Add missing expanded schema fields to 5 portals (#1612)

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

## Changes

Added the following fields to each portal:
- portal_type: Type of portal (creative-tool, knowledge-base, etc.)
- world_category: Category (development, documentation, social, etc.)
- environment: Deployment environment (local, production)
- access_mode: Access level (operator, visitor)
- readiness_state: Current state (online, standby)
- readiness_steps: Progress tracking for readiness stages
- blocked_reason: Reason if blocked (null if not blocked)
- telemetry_source: Source identifier for telemetry
- owner: Portal owner
- destination.action_label: Label for portal activation

## Verification

All 8 portals now have complete schema:
- morrowind ✅
- bannerlord ✅
- workshop ✅ (NEW)
- archive ✅ (NEW)
- chapel ✅ (NEW)
- courtyard ✅ (NEW)
- gate ✅ (NEW)
- playground ✅

## Testing

test_portals_json_uses_expanded_registry_schema: PASS

Fixes #1511
Closes #1612
