ISSM NUOPC prerelease deployment

[reillyja]

This is a first pass at adding a NUOPC cap to the ISSM deployment. Local Spack build runs MISMIP successfully using the issm.exe.

Still need to test a mediator driven ISSM toy run through the added NUOPC cap.

Usage Instructions

access-issm, defined in spack.yaml, will be deployed to Gadi as:

• 2026.05.19 as a Release (when merged).
• pr42-1 as a Prerelease (during this PR).

This Prerelease is accessible on Gadi using:

module use /g/data/vk83/prerelease/modules
module load access-issm/pr42-1

When using the above modules, the binaries shall be on your $PATH.

For advanced users, this Prerelease is also accessible on Gadi via /g/data/vk83/prerelease/apps/spack/1.1/spack in the access-issm-pr42-1 environment.
Due to inode-saving measures, one will have to manually untar the environment metadata before environment activation with tar -xf .spack-env .spack-env.tar. It will require one to have write privileges.
