feat: Complete VS-03 BE+ASYNC - Market Data Ingestion (Batch 2 - 5/7)

Browse Source 
Implements market data ingestion REST API and Hangfire scheduler:

✅ BE (REST Endpoints):
   - POST /api/market/ingest: Trigger data ingestion (202 Accepted)
   - GET /api/market/ingest/{jobId}: Check ingestion status
   - Idempotency: By (dataSource, fromDate, toDate)
   - Audit: Correlation ID tracing

✅ ASYNC (Hangfire Job):
   - Daily 9:00 KST scheduling
   - Flow: Fetch → Validate → Normalize → Persist → Event publish
   - MarketDataSyncedEvent: Published when sync completes
   - Idempotency: No re-run for same date range
   - Status tracking: Queued → Running → Completed/Failed

✅ Application Handler:
   - IMarketDataIngestionService: Orchestrates ingestion
   - Job scheduling with correlation ID
   - Event publishing to outbox
   - Status persistence to ingestion_jobs table

✅ Abstractions:
   - IMarketDataDataSourceClient: KRX/OpenDart/Stub
   - StubMarketDataClient: Testing implementation

AGENTS.md v16.0 compliance:
✅ Idempotency: By date range (same range = no re-run)
✅ Traceability: CorrelationId + JobId tracking
✅ Audit: All state changes logged
✅ Safety: Transaction-safe persistence
✅ Maturity: Contract-first design

Phase 2 Progress: Batch 2 (5/7 COMPLETE - missing FE + TESTOPS)

Next: VS-04~08 or Phase 3 validation
