Display an error if a proof request hits a validation error

Not sure if bug or nice-to-have feature request (probably the latter)

Description of feature / user story

If a connectionless (not sure what happens if using a real connection) proof request scanned fails with a validation error, would be nice I think to have feedback to the user that it fails.

Currently a validation error from Credo about the proof being malformed will just sit on the making connection spinner.

Acceptance Criteria

A (friendly? or developer-y?) error message to the user that this proof will not work rather than possibly confusing "waiting for connection" spinning.

I make a mistake in my proof like below, using a string when a Int is needed or something in p_value

{
  "name": "CSB Transcriber",
  "version": "0.0.1",
  "requested_attributes": {
  blah blah blah
 }
  },
  "requested_predicates": {
    "req_pred_0": {
      "name": "contract_start_dateint",
      "restrictions": [{ "schema_name": "contractor-credential" }],
      "p_value": "20240913",
      "p_type": "<=",
      "non_revoked": { "from": 1726269311, "to": 1726269311 }
    }
  },
  "nonce": "989457181219949169483799"
}

If I use that proof in VCAuthN either in a connectionless invitation, or an Out-Of-Band, then what I see in the BC Wallet when I scan the QR code is:

And that just keeps going.

Using remote debugging I can see these validationErrors errors throw from the BC Wallet.
