Regional update coupled names

[ashjbarnes]

This builds on @kieranricardo 's recent branch (update-coupled-names). The only difference is that I've needed to

1. turn of CICE
2. alter the cmeps mediator file to remove the hardcoded ice fields in the mediator, so that when ice is turned off for a regional configuration, the mediator doesn't fail when it can't find ice fields

Eventually we want to set things up so that we can share the regional and global cm3 code, but for now I'm trying to keep the rcm3 exe as close as possible to cm3 with a few lines of commented out code sprinkled throughout:
CMEPS, UM and ACCESS-CM3-CONFIGS

See https://github.com/ACCESS-NRI/access-cm3-configs/issues/38

Thanks @anton-seaice for all his help!

Usage Instructions

access-om3, defined in spack.yaml, will be deployed to Gadi as:

• 2025.08.999 as a Release (when merged).
• pr208-4 as a Prerelease (during this PR).

This Prerelease is accessible on Gadi using:

module use /g/data/vk83/prerelease/modules
module load access-om3/pr208-4

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-om3-pr208-4 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.

Configuration Information

This Prerelease is deployed using:

• access-nri/spack on branch 1.1
• spack/spack-packages version 383e969358c951abe17623696083e6f862c4488e
• access-nri/access-spack-packages version 2026.02.002
• access-nri/spack-config version 2026.02.003

If the above was not what was expected, commit changes to config/versions.json in this PR, or propose changes to build-cds config/settings.json.
