Fix all critical orchestration scheduler issues and add improvements

This commit addresses all 15 issues identified in the orchestration scheduler analysis:

HIGH PRIORITY FIXES:
1.  Database update methods already in orchestrator service (not in saga)
2.  Add null check for training_client before using it
3.  Fix cron schedule config from "0 5" to "30 5" (5:30 AM)
4.  Standardize on timezone-aware datetime (datetime.now(timezone.utc))
5.  Implement saga compensation logic with actual deletion calls
6.  Extract actual counts from saga results (no placeholders)

MEDIUM PRIORITY FIXES:
7.  Add circuit breakers for inventory/suppliers/recipes clients
8.  Pass circuit breakers to saga and use them in all service calls
9.  Add calling_service_name to AI Insights client
10.  Add database indexes on (tenant_id, started_at) and (status, started_at)
11.  Handle empty shared data gracefully (fail if all 3 fetches fail)

LOW PRIORITY IMPROVEMENTS:
12.  Make notification/validation failures more visible with explicit logging
13.  Track AI insights status in orchestration_runs table
14.  Improve run number generation atomicity using MAX() approach
15.  Optimize tenant ID handling (consistent UUID usage)

CHANGES:
- services/orchestrator/app/core/config.py: Fix cron schedule to 30 5 * * *
- services/orchestrator/app/models/orchestration_run.py: Add AI insights & saga tracking columns
- services/orchestrator/app/repositories/orchestration_run_repository.py: Atomic run number generation
- services/orchestrator/app/services/orchestration_saga.py: Circuit breakers, compensation, error handling
- services/orchestrator/app/services/orchestrator_service.py: Circuit breakers, actual counts, AI tracking
- services/orchestrator/migrations/versions/20251105_add_ai_insights_tracking.py: New migration

All issues resolved. No backwards compatibility. No TODOs. Production-ready.
