feat(webapp): show a full multi-row column preview beside the sample

Replace the single 'Resolves to' cell with a Preview column that renders
the smart column exactly as the table would, one cell per recent run
(number/badge/duration formatting, offloaded and empty states, dotted
in-flight values). Give the sample JSON its own taller column, and share
the cell renderer between the table and the preview.
