Refactor public/ Directory Components to useK8sWatchResource(s)

*Description: *Migrate all components within the /public directory from the legacy <Firehose> wrapper to the modern useK8sWatchResource and useK8sWatchResources hooks.

*Scope: *~19 files identified in the investigation.

AC:

• Functional Parity: All 19 identified components maintain existing behavior for resource fetching, loading states, and error handling.

• Hook Migration: The legacy <Firehose> component and its associated Higher-Order Component (HOC) props are removed and replaced with useK8sWatchResource or useK8sWatchResources.

• Dependency Handling: Components utilizing connectToFlags or multiple resource instances (e.g., cron-job.tsx) successfully resolve data without regressions.

• Test Alignment: Unit and integration tests (including firehose.spec.tsx) are updated to reflect hook-based data fetching and are passing.
