The hydra node can publish hydra scripts via blockfrost using `--blockfrost`

[noonio]

Why

As Hydra moves towards using Blockfrost as a chain layer, we need to extend the functionality to publish Hydra scripts via the Blockfrost API. This follows up on #1305 and builds upon our initial exploration on #1631.

What

Introduce the capability to publish Hydra scripts using Blockfrost as follows:

mkdir -p blockfrost-demo/
curl localhost:4001/protocol-parameters > blockfrost-demo/protocol-parameters.json

function publishScripts() {
  nix run .#hydra-node -- publish-scripts \
    --blockfrost 0.0.0.0:4001 \
    --project-path "file_path_project_token_hash" \
    --cardano-signing-key blockfrost-demo/wallet.sk
}

export HYDRA_SCRIPTS_TX_ID_ON_BLOCKFROST="$(publishScripts)"

How

Taking the inception spike as inspiration, we need to:

• [ ] Refactor PublishOptions to support Blockfrost options:

  newtype PublishOptions = PublishOptions
    { publishChainConfig :: ChainConfig }
    deriving stock (Show, Eq)
  
  data ChainConfig
    = Offline OfflineChainConfig
    | Direct DirectChainConfig
    | Blockfrost BlockfrostChainConfig
    deriving stock (Eq, Show, Generic)
  

The path to the Blockfrost project token hash will be passed as part of these new options.

• [ ] Add Hydra/Chain/Blockfrost/Client.hs to handle transaction building using the Blockfrost API.

• [ ] Add Hydra/Chain/Blockfrost/ScriptRegistry.hs to manage Hydra script publishing via Blockfrost.

• [ ] Extend hydra-node/Main.hs to support publishing scripts using the modules above.
