fix(prover_cli): Fix Minor Bugs in Prover CLI (matter-labs#2264)

This PR fixes bugs in the Prover CLI:
- The status command was not displaying correctly for more than one
batch.
- The witness job status was incorrectly set to "in progress" when some
batches were in the queue and others were waiting for proofs.
- The config command failed if there was no configuration file. Now, it
creates one if it’s not found.
