Surface failed refreshes instead of swallowing them

Favourites and stream profiles were refreshed inside a bare runCatching,
so when they failed nothing was logged and the app just showed a stale
cached list. An expired login now always raises the re-login screen, even
when cached channels could still be displayed, and the settings gained a
"Senderliste neu laden" row for a manual retry.
