fix(web-read-card): mark read-row summary chrome jscpd:ignore

The keyed toolviews (read, file-mutation, web) each draw the same ToolRow
summary-line chrome; the read row's copy trips the duplication gate against the
file-mutation row. Extracting the shared row is a separate change tracked for
all rows at once, so this scopes the exemption to the read row's block.
