feat(watchlist): the ClubLog expedition enrichment — phase 2 lands

clublog.org/watch.php, per entry: the DXpedition flag, OQRS, LiveStream, the
log's QSO total and the last-24h rate — the fields the schema has carried since
phase 1. Refreshed on DXHunter's own cadence (hourly for expeditions,
six-hourly for the rest), two at a time with a breath between requests: the
application API key is shared by every install, so a hundred-entry list must
read as a trickle at ClubLog's end. Nothing to configure — OpsLog's own key,
already used for cty and Most Wanted, serves.

A starred pattern is asked about by its base (ClubLog has no log for VK9*).
The card gains the 24h rate beside the QSO total and the Live link to the
expedition's stream.
