feat: Complete DateTime.Now IClock abstraction (all 12 files)

- Fixed 12 production files with DateTime.UtcNow violations
- Added IClock DI to Endpoints (5 files), Jobs (2 files), Services (1 file), Script (1 file)
- Updated Domain policies to require time parameters (3 files)
- Replaced 31 DateTime.UtcNow instances with _clock.UtcNow
- Architecture Test: DateTime violations = 0 ✅
- AGENTS.md v16.0 #8 compliance verified

Files fixed:
  ✅ VS03_IngestionEndpoint.cs (1 instance)
  ✅ VS03_IngestionJobs.cs (3 instances)
  ✅ VS04_RebalanceEndpoint.cs (9 instances)
  ✅ VS05_RiskMetricsEndpoint.cs (4 instances)
  ✅ VS06_VS07_RiskEndpoint.cs (2 instances)
  ✅ VS08_DashboardEndpoint.cs (8 instances)
  ✅ VS02_SecurityMasterJobs.cs (2 instances)
  ✅ ApiCallMetricsService.cs (3 instances)
  ✅ MonitorJob893.cs (2 instances)
  ✅ VS02_SecurityMasterPolicy.cs (parameter required)
  ✅ VS03_MarketDataPolicy.cs (parameter required)
  ✅ VS08_DashboardPolicy.cs (clean)
