Deploy verification prints out too much on each iteration of checking

The full deployment JSON is being printed out during deployment validation. We should remove this and only add it back when we have a way to enable "debug" mode or log levels for this step.

Example log snippet here (it is 100x longer than this):

Search the Java sources for deployment validation or verification and identify the logging path that emits the fetched deployment JSON. Reproduce a validation run to confirm the excessive output, then verify that normal output no longer includes the full JSON while the verification result still appears; run any related tests found near that code.
