Return errors from signing key generation and signing (#835)

* Propagate signing key generation and signing failures through Env

* Preserve credentials and clear assertion state on signing failure

* Return opaque errors from signing traits

* Isolate crypto failure injection in test implementation

* Make test crypto failure guards order independent

* Make crypto failure tests focus on one behavior

* Simplify signing error propagation and failure tests

* Reuse set_batch_attestation helper in test_process_register

Make the helper return the attestation it configures, so the register
test can keep asserting on the stored certificate. Refactors the only
remaining test that set batch attestation inline, as suggested in
review.
