test(plugin-consortium-manual): fix port binding - multiple API servers

1. The ConnectRPC port defaults to 6000 in the API server so for test cases where multiple
instances of the API server are created and started, we need to specify the ports
explicitly in the API server config so that they don't clash with each other casusing the
test to fail.
2. The fix here was to simply bind to port 0 for all the ConnectRPC listeners which
eliminated the possibility of a clash and the test is passing once again.
3. I also snuck in a quality of life improvement for contributors: the API server will no
longer log the entire details of the fastify server that is being used for CRPC thereby
reducing the verbosity of the logs by a wide margin.

Crash logs that revealed the bug in the test case:
