### What changes were proposed in this PR? Bulk-uploading many files to a dataset was extremely slow (~1,100 files took ~12 minutes) because the Pending and Finished lists fully re-rendered on every change-detection pass, on the same thread driving the uploads (root cause detailed in #5586). As proposed in the issue: replace the `queuedFileNames` getter with a cached field refreshed only when the queue changes, virtualize the Pending and Finished lists with `cdk-virtual-scroll` so only visible rows are in the DOM, and add `trackBy` to both lists. Screen recording of a successful 1,100-file upload with the fix: ### Any related issues, documentation, discussions? Closes #5586. ### How was this PR tested? New unit specs (12 tests): `npx ng test --watch=false --include "**/dataset-detail.component.spec.ts" --include "**/user-dataset-staged-objects-list.component.spec.ts"`. Full dashboard suite: `npx ng test --watch=false --include "src/app/dashboard/**/*.spec.ts"` — 346 passed. Manually verified on the local dev stack: 1,100 files upload successfully with the UI responsive throughout (recording above). ### Was this PR authored or co-authored using generative AI tooling?
