Reduce redundant metadata API requests in dashboard pages

[dolliecoder]

Summary

This PR reduces redundant metadata API requests across the Jobs, Pods, and PodGroups pages.

Previously, metadata fetches such as fetchAllNamespaces() and fetchAllQueues() were coupled with data-fetch effects that depended on dynamic query callbacks (fetchJobs, fetchPods, fetchPodGroups). Since these callbacks are recreated when search, filters, or pagination state changes, the metadata endpoints were being unnecessarily re-requested multiple times.

Changes

• Separated metadata fetches into dedicated mount-only useEffect hooks

• Preserved existing dynamic data-fetch behavior for jobs, pods, and podgroups

• Reduced unnecessary requests to:

  • /api/namespaces
  • /api/all-queues

Files Updated

• frontend/src/components/jobs/Jobs.jsx
• frontend/src/components/pods/Pods.jsx
• frontend/src/components/podgroups/PodGroups.jsx

Result

• Reduced redundant API requests during search/filter interactions
• Improved frontend request efficiency
• Preserved existing UI behavior and application flow

Testing

Verified that:

• search and filtering continue to work correctly
• pagination behavior remains unchanged
• metadata requests are no longer repeatedly triggered on query state updates
• no UI regressions were introduced

Code Review

This pull request refactors the data fetching logic in the Jobs, PodGroups, and Pods components by moving metadata fetching (namespaces and queues) into separate useEffect hooks that run only on mount. Feedback was provided to include cleanup mechanisms in these new hooks to prevent potential state updates on unmounted components and to consider the impact of moving these fetches out of the manual refresh cycle.
