Add EnableP2P to the config file. Improve message when running the custer.

Enhances the `cardano-testnet` user experience by refining startup output.

- Clearer instructions for interacting with the testnet, including
  `CARDANO_NODE_NETWORK_ID` and `CARDANO_NODE_SOCKET_PATH` exports.
- Use absolute paths in the outputs for socket path

Improve messages when running the testnet

The HTTP call fetching mainnet protocol parameters from https://github.com/input-output-hk/cardano-parameters/blob/main/mainnet/parameters.json had no retry logic, so a transient network or TLS error would kill the testnet setup with an opaque exception. Retry up to 3 times with a  2-second delay, logging each attempt to stderr, and wrap the final failure in a descriptive error.
