Hiep Ha VanandClaude Sonnet 5 40b12ecb15 refactor(monitoring): N2 - tach monitoring_tab.py, CanonicalAuditLogger, MonitoringQueryService, go circular import, sandbox matrix
- ui/monitoring_tab.py (1546 dong) tach thanh presentation/monitoring/**
  (container + 7 tab/card + shared helper), ui/monitoring_tab.py con lai
  re-export shim de app.py khong doi.
- infrastructure/telemetry/audit_logger.py: CanonicalAuditLogger, core/audit_log.py
  thanh wrapper mong, tuong thich nguoc 100% voi schema .jsonl cu.
- application/monitoring/monitoring_query_service.py: MonitoringQueryService
  read-only, filter/sort/pagination, khong import PySide6.
- Go circular import model_pricing<->usage_tracker va agent_security<->
  agent_security_alert (core/agent_security_types.py moi).
- infrastructure/sandbox/sandbox_capabilities.py: SandboxCapabilityMatrix
  theo OS (Windows/Linux/macOS), chua dau noi vao core/sandbox_manager.py.
- conftest.py: sua loi checkout khong ten cowork_local khien pytest import
  nham thu muc khac.
- 77 test moi, 167/167 pass. QA da xac nhan UI/business logic khong doi
  (xem evidence/report/unified_report.html).
