[mBMON] new monitor wrapper script auto-filling run ID and starting slurm job

Commit to protect this QoL improvement tested and used during the latest 1-day mCBM beamtime:

• lower risk of human errors while copy-pasting the run ID after strting a new run
  => decreased load on shifters
• better tracking of monitor state as easy to see if job still running with squeue
• lower risk of forgetting to stop the monitor at end of beamtime thanks to max job duration
