The custom/authorized-value status branch concatenated row.status
directly into a class="..." attribute string. escape_str() only
escapes &, <, > (not quotes), so a status code containing a double
quote could still break out of the attribute.
Build the status <span> via DOM APIs instead, the same way the
reason field was fixed: fixed statuses get a hardcoded class, and
the free-form status code goes into a data-status attribute via
dataset, which the DOM escapes safely regardless of content.
