fix(validation): Resolve PSA collisions in base tests & fix boolean evaluation

- Apply PSA cleanup and variable scope fixes to `base-integration-test.yml` to resolve collisions in GKE/Lustre tests.
- Add `| bool` filter to `use_fixed_vpc` evaluation in both base and Slurm playbooks to ensure string representations of booleans are correctly parsed.
- Simplify firewall rule network parameter in base playbook to use `actual_network` directly.
