The BTCPayServer hub entry was using `cfg.services.bitcoin` as its `enabled` flag, which is `true` in node mode. This caused the Hub UI to show BTCPayServer as enabled even though the underlying NixOS service is correctly gated on `cfg.web.btcpayserver` (which defaults to `false` for the node role via role-logic.nix). Change the enabled field to `cfg.web.btcpayserver` so the Hub UI accurately reflects the service state and BTCPayServer is disabled by default on a fresh node-only install.
