What is the difference between a principal.Signer and ucan.Signer? It looks like principal.Signer is a ucan.Signer, plus some other methods? Would it be possible to align on just a single interface here and everywhere else?

We only need something that can sign a message here, we don't need the other methods that signers that are principals also have (like accessing the DID or encoding the key to bytes etc.).

This PR adds a validation method for the configured delegation that enables piri nodes to cache claims with the indexer.
The delegation is validated at server startup to prevent failures from occurring after data is stored on the node.
The delegation is validated by calling the ucanto validator
Accessmethod with a dummy invocation.
