preindustrial+emissions: update to ndep v2

[blimlim]

1. Summary:

This PR adds the Ndep v2 dataset, as required for the new production runs.

It also reverts the restart for the preindustrial+emissions configuration to /g/data/vk83/prerelease/configurations/inputs/access-esm1p6/modern/pre-industrial-emissions/restart/2026.02.23. This matches the year 1 restart for the preindustrial+concentrations simulation, with the 3D CO2 fields reset to 4.3189e-4.

2. Issues Addressed:

• Update to Ndep V2 #688

3. Dependencies (e.g. on payu, or model)

This change requires changes to (note pull request(s) where relevant):

• workflow manager (payu):
• model deployment (ACCESS-ESM1.6):
• model component or library dependency:
• input workflow:

4. Ad-hoc Testing

What ad-hoc testing was done? How are you convinced this change is correct (plots are good)?

5. CI Testing

• !test repro has been run

6. Reproducibility

Is this reproducible with the previous commit? (If not, why not?)

• Yes
• No - !test repro commit has been run.

Change in restart and nitrogen inputs change answers

7. Performance

Has the model performance (say, throughput of model-years/wall-day) changed?

• Yes
• No
• N/A (if selected, please add a brief explanation why performance testing is not necessary for this PR)

Change in input/restart not expected to change answers.

If yes, provide the numbers from your testing. Is the performance better or worse?

8. Manifests

Have you changed the executable, the input files and/or the restart files?

• Yes
• No

If yes, have you updated the manifests?

• Yes
• No

To update the manifests, run payu setup (in a cloned copy of your feature branch) with reproducibility tests turned off:

manifest:
  reproduce:
    exe: false
    input: false
    restart: false
runlog:
  enable: false

Then commit the newly created manifest files (under manifests/) only to the branch for this PR.

9. Documentation

Is the documentation updated?

• Yes
• N/A

10. Merge Strategy

• Merge commit
• Rebase and merge
• Squash

The executable was updated in the prev I guess - otherwise LGTM

[blimlim]

Thanks @JhanSrbinovsky, yep the executable was updated in #678
