## mkUserServers — silent fallback on all-disabled

See comment on `mkUserServers`. If filtering routers by `enabled && role` yields an empty list, `fromMaybe srvs` falls back to *all* routers regardless of enabled/role status. This prevents a configuration where all routers are disabled from leaving the user with no routers — but means disabled routers can still be used if every router in a role is disabled.
