Pull Request Overview

This PR refactors the installer scripts by moving PBS options into the submission wrapper, parameterizing the reservation ID, and cleaning up the helper script.

• Require a second argument (reservation-id) in run_setup.sh and pass it to qsub
• Relocate PBS flags (-P, -q, -o, -e, -l) into run_setup.sh
• Strip all #PBS directives from qsub_setup.sh
