FOLLOW-UP from issue #89 / PR #161. Issue #89 section 3 asked the bulk modal to show the current value distribution per field across selected items (e.g. "Status: 8 Owned, 4 Want"). PR #161's modal edits fields directly; it does not render value distribution. Add it as a UX refinement read from the selected rows in the client.
