fix(review): address reviewer concerns from PR #661

- Replace brittle createdAt===updatedAt isNew() check with a 7-day
  recency window (created within last 7 days = new)
- Add createdAt/updatedAt to searchItem fixture in page.server.spec.ts
  and assert they are propagated to recentDocs
- Replace null timestamps in DocumentListItem test fixtures with a fixed
  LocalDateTime to satisfy the @Schema(required) contract
