Fix common error in system tests

[bogdanfazakas]

Error: Ocean CLI Paid Compute
should start paid compute on compute dataset and algorithm:
Error: Could not find Job ID in the output
at Context. (file:///home/runner/work/ocean-node/ocean-node/ocean-cli/test/paidComputeFlow.test.ts:130:19)
at process.processTicksAndRejections (node:internal/process/task_queues:95:5)

The failure appears to be related to parsing or assumptions about CLI output, not necessarily the compute job itself.

Choose one of the following paths:

• Option A: Investigate & Fix (Time-boxed) up to 30 minutes investigating the root cause & Fix the test or CLI output handling

• Option B: Remove or relax the test assertion that requires a jobId in the CLI output
