TBv3: Fix version comparison diff view filters not updating

[jamlung-ri]

Summary

The concept-change filters in the source version comparison diff view (minor change, major change, new, retired) do not reliably update the concept list when selected. Clicking a filter appears to have no effect.

Current Behavior

1. User opens the version comparison view for a source (/:repo/compare-versions)
2. User selects a filter (e.g., "minor change" or "major change") to scope the concept list
3. The concept list does not update — the filter click is ignored or the list fails to re-render

Expected Behavior

Selecting a filter category updates the concept list to show only concepts that match that change type between the two selected versions.

Notes

• Observed during a demo on 2026-05-20
• CompareVersions.jsx and VersionResourcesComparison.jsx have not been touched since the original ocl_issues#1853 implementation — no follow-up fixes have been applied
• This bug affects the usability of the comparison view as a whole and should be resolved alongside or before extending comparison to collections (ocl_issues#2532)

Decision: decision/human-review
Type: type/bug
Signals: signal/low-risk, signal/small-scope

Moderate complexity involving UI state management and filter logic across a few related files. Clear bug description with reproduction steps but missing technical details about the root cause. Low risk since it's a UI filtering issue that doesn't affect data integrity.
