Feat/poam phase1

[AKAbdulHanif]

Summary

• Adds a basic POAM Items list page to exercise the API filters end-to-end.
• Route & View

New authenticated route: /poam-items

• View implements filter inputs (status, sspId, riskId, deadlineBefore) and renders table rows
• Code:
  • Router: router/index.ts
  • View: CCFPoamItemsListView.vue

Implementation Notes

• Uses existing API composables (useApi/useFetch) to call /api/poam-items.
• Minimal styling; intended as a functional starting point for Phase 1.
• Next steps: add create/edit forms and milestone operations in the UI.

How to Verify

• Open http://localhost:8000/poam-items
• Apply filters and confirm the list updates (requires corresponding data in API)
