feat(node): show a live daemon console tail on the initializing overlay

Browse Source 
The full-node Console tab already streams the daemon's output, but during
startup the user is held on the loading overlay (wallet-data tabs are blocked),
so they can't watch progress without navigating away. Surface the last few
console lines the node printed (UpdateTip height=…, "Verifying blocks…", etc.)
directly under the status/description on the overlay while initializing or
warming up, so progress is visible where the user is already looking.

Full-node only (guarded on daemon_controller_); each line is trimmed and
ellipsis-truncated to one row. Reuses DaemonController::recentLines().
