The Pagination coverage is relevant, but this PR also carries the preferred-export-format hook test that has already been merged via #634. Please rebase on latest main and remove frontend/testing/unit/hooks/usePreferredExportFormat.test.ts from this PR so it stays focused on Pagination coverage only.

Hi @utksh1 , thank you for the review! I'm working on this right now.
I will rebase on latest main and remove frontend/testing/unit/hooks/usePreferredExportFormat.test.ts from this PR since it was already merged via #634. This PR will then focus solely on Pagination coverage.
I'll push the updated branch shortly. Please allow me a few hours to complete the rebase and cleanup. Thank you for your patience!

Hi @utksh1, I've cleaned up this PR. It now contains only the Pagination test coverage. The branch was rebased on latest main and all unrelated files (including usePreferredExportFormat.test.ts already merged in #634) have been removed. Please re-review when you have a moment. Thank you!

The latest net diff is now focused on Pagination component coverage only, resolving the earlier unrelated hook-test concern. Approved pending a fresh branch update.
