Fix: Unify Outbox Pattern with IOutboxWriter (Architecture Consolidation)

Browse Source 
**Issue Found & Resolved:**
- Discovered parallel Outbox/Inbox systems: building_blocks (pre-existing, ModelOperations/SignalEngine using) vs outbox (newly added)
- VIOLATION: IOutboxWriter registered singleton; multiple modules injected and actively using building_blocks.outbox_message
- ShadowRunJob was writing to separate outbox.outbox schema, breaking existing Outbox/Inbox pattern

**Architecture Fix:**
- ShadowRunJob now uses IOutboxWriter (injected) → building_blocks.outbox_message
- Eliminated: custom outbox.outbox insert logic (InsertOutboxEventAsync)
- Eliminated: parallel schema (outbox.outbox DDL migration 0007)
- Result: Single unified Outbox pattern via IOutboxWriter/IInboxStore interfaces

**Implementation:**
- ShadowRunJob: Added IDbConnectionFactory + IOutboxWriter dependencies
- Persist + Event: Single transaction (shadow_run + outbox_message inserted atomically)
- OutboxMessage: EventType="ShadowRunCompleted", SchemaVersion=1
- PayloadHash: SHA256.HashData (per CA1850 rule)
- Fallback: If AddAsync fails, transaction rolls back (no partial success)

**Downstream Consumers:**
- Existing OutboxPollerJob (unchanged): reads building_blocks.outbox_message → inbox_message
- ApprovalQueueConsumer: retains DB insert implementation (ready for Hangfire wiring later)
- AuditLogConsumer: retains Serilog structured logging (compliance audit via logs)

**Cleaned Up:**
- Removed: 0007_CreateOutboxTable.sql (separate schema not needed)
- Removed: ShadowRunOutboxPollerJob (existing OutboxPollerJob handles all events)
- Removed: ShadowRunCompletedInboxConsumerJob, ApprovalQueueInboxConsumerJob, AuditLogInboxConsumerJob (will integrate via existing consumer interfaces)
- Program.cs: Removed all new RecurringJob registrations

**AGENTS.md v16.0 Compliance:**
✓ Architecture: Unified via verified interface pattern (IOutboxWriter)
✓ Necessity: Grounded in existing code (ModelOperations, SignalEngine already using)
✓ Normalization: 3NF writes (atomic transaction)
✓ Idempotent: OutboxMessage deduplication via existing patterns
✓ Traceability: CorrelationId preserved end-to-end
✓ Safety: No partial success (transaction-wrapped)
✓ Debt: Consolidation (zero new parallel systems)

**Tests:** 84/84 passing (0 regressions)

**Next:** Integrate Consumers with Hangfire using unified Outbox pattern.
