Preload Cardano transactions based on Aggregator's Signing Capability

[dlachaume]

Content

This PR includes a control that allows the execution of the preloading of the Cardano transactions on both the Aggregator and Signer nodes.

• On the Aggregator, the list of the allowed signed entity types in the configuration is checked to verify if the CardanoTransactions is included.
• On the Signer, the root route / of the Aggregator is called to verify if the CardanoTransactions signed entity type is part of its signing capabilities.
