Pull request description:

  ## Additional Information

  * When backporting [bitcoin#27452](bitcoin#27452) in `feature_anchors.py`, `P2P_SERVICES` (`NODE_NETWORK | NODE_HEADERS_COMPRESSED`) has been replaced with `NODE_NETWORK` as the former evaluates to a value greater than `256` (specifically `2049`), which causes test failure. The replacement value is acceptable as `NODE_NETWORK` is the desired service flag expected by Dash Core ([source](https://github.com/dashpay/dash/blob/779e4295ad253bf909a7c45ec02743e580abc61b/src/protocol.cpp#L249-L254)).
