R-621: the hold panel points at the log the hold kept

A held app's page now says, inside the hold panel, that the app's own log from
before it was stopped was kept, with a Napló link to the logs page that serves
it (0b93e1a). Shown only for an update hold with a non-empty kept log
(Manager.HoldLogKept). New copy through the bundle (hu + en), parity case
app_info_hold_log captured when born.
