fix: remove useMemo after early returns to fix React error #310

The useMemo hook was placed after conditional early returns in
RecordDetailView, violating React's Rules of Hooks and causing
"Rendered fewer hooks than expected" (React error #310). Replaced
with an IIFE to keep the same Set-based dedup logic without hooks.
