Pull request overview
This PR expands frontend unit test coverage for UserDatasetFileRendererComponent to better exercise lifecycle-triggered reload behavior, object URL cleanup, viewer selection logic across multiple file types, and defensive guards for oversize/unsupported previews.
Changes:
- Added
ngOnChangestests to confirm reload triggers forfilePathchanges and the(did + dvid)pair, and non-triggers for unrelated/partial changes. - Added cleanup tests verifying object-URL revocation in
ngOnDestroyandturnOffAllDisplay. - Added
reloadFileContenttests covering viewer selection for image/video/audio/markdown/json/csv, plus oversized/unsupported-blob guard behavior.

Use realistic SimpleChange(previous, current, firstChange) inputs for the
ngOnChanges tests instead of empty {} placeholders, set safeFileURL to an object
with a toString() (matching the SafeUrl runtime) rather than a raw string cast,
and drop the undefined-as-never cast on the notification warning spy.
