fix: update spack role deps from gcc-7 to gcc (Ubuntu 22.04+)

- spack: Replace gcc-7/gfortran-7 with unversioned gcc/gfortran
- Remove abims_sbr.singularity from requirements.yml (dead project)
- Remove singularity_wrapper from molecule CI (broken Galaxy dep)
- Re-add command:/sbin/init + tmpfs:/run (without /tmp) for roles
  that need systemd: slurm, nis_client, rsyslog_client/server, nfs,
  cachefilesd, nvidia_dcgm. The key fix: /tmp is NOT mounted as tmpfs,
  so systemd won't clean it and break Ansible's temp dirs.
