Qobuz login was only available on the Downloads tab when Qobuz was
selected as download source. But Qobuz credentials are also needed
for the enrichment worker which runs independently. Users saw
"Connect Qobuz in Settings" on the dashboard but couldn't find it.
Adds a Qobuz section to Settings → Connections (same pattern as
Tidal's existing Connections section). checkQobuzAuthStatus() now
syncs both the Connections and Downloads tab sections. Login from
either tab updates both. No backend changes — same API endpoints.
