feat: enhanced details in agent call errors

[krpeacock]

Description

Motivated partially by efforts to find the root of the mysterious "invalid signature" errors, but also to enhance developer experience in general, this will provide useful information for debugging purposes included in the Error thrown from a failed call.

Now includes:

• response
• requestId (hex)
• sender_pubkey (hex)
• sender_sig (hex)
• ingress_expiry (string)

New response:

{
  message:
    "Error while making call: Server returned an error:\\n  Code: 400 (Bad Request)\\n  Body: Invalid signature: Invalid basic signature: Ed25519 signature could not be verified: public key 3b6a27bcceb6a42d62a3a8d02a6f0d73653215771de243a63ac048a18b59da29, signature 00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000, error: A signature was invalid\\n\\n",
