* Translate failed authentication errors
When AES-GCM authentication fails, webcrypto returns a very generic error. The
same error is thrown for invalid length inputs, but our earlier checks in
decryptProfile should rule out those failure modes and leave us safe to assume
that we either had bad ciphertext or the wrong key.
