PR #13230: across several companies, the prospects list says whose each lead is

PR #13230 at 3c4c0dc511. The branch's dev server ran against the stage table (read-only) with a staff session. Only the table's header row is captured, so no names are shown.

Two companies picked

Headers: Prospect, Property, Company, Stage, Source, Clara, Created, Last Activity

One company picked (unchanged)

Checked in the page: with two companies picked the header row has Company after Property, and with one company it does not. Both views listed 50 rows. The column is the shared companyColumn that Work Orders, Tenants, Turnovers, Collections and Properties already use.
