[#1175] services/sign: Convert error
to status return
In previous implementation `SignService` converted all `error` values to `INTERNAL` server failure status. That was done for simplification only. There is a need to transmit status errors as corresponding status messages. Make `SignService` to unwrap errors and convert them to status message during writing to the response. Non-status errors are converted to `INTERNAL` server failures. Status errors can also be wrapped in the depths of the executable code, so `SignService` tries to unwrap them.
