prevent logger from truncating response from rust verifier service in case of an error

[fullkomnun]

Unsure if this qualifies as a bug fix since it fixes the logging..

Motivation

Error responses received from rust verifier service currently get truncated by the logger even though IO.inspect(error, limit: :infinity, printable_limit: :infinity) is being used. I applied the following pattern that saves the original logger's 'truncate', sets it to ':infinity' for logging the response, then restores it as done in apps/explorer/lib/explorer/repo.ex.

Changelog

• Prevent logger from truncating response from rust verifier service in case of an error
