perf: memoize expensive list computations + memo on grid/list items

Results.tsx:
- useMemo: filter + sort in one pass (was 7 separate array iterations per render)
- useMemo: platform/maison/future/missingData counts in single for-loop
- Fix: move queryClient.invalidateQueries from render body into useEffect

Properties.tsx:
- useMemo: wrap applyFilters() call (was full copy+sort on every render)
- useMemo: compute matchReady/criticalGaps/lowConfidence/staleOrOutdated/
  allMissingFields in a single for-loop (was 5 separate filter passes)

ReminderFeed.tsx:
- useMemo: wrap applyFilters() call
- useCallback: resetFilters (passed to ReminderEmptyState)

PropertyIntelligenceCard, ReminderListRow:
- React.memo: grid/list items no longer re-render when unrelated parent
  state changes (e.g. selectedId, filter UI state)

tsc --noEmit passes with zero errors
