Correctly transfer the co2luc subcategories in the coupling

[dklein-pik]

Purpose of this PR

Use the correct domain (all_enty instead of enty) for the set emiMacMagpieCO2Sub to actually transfer the co2luc subcategories in the coupling. Until now, the set-domain combination was empty, no emissions were transferred, and the values taken from the lookup table remained unchanged.

Type of change

Parts concerned

• ☑️ GAMS Code
• ◻️ R-scripts
• ◻️ Documentation (GAMS incode documentation, comments, tutorials)
• ◻️ Input data / CES parameters
• ◻️ Tests, CI/CD (continuous integration/deployment)
• ◻️ Configuration (switches in main.gms, default.cfg, and scenario_config*.csv files)
• ◻️ Other (please give a description)

Impact

• ☑️ Bug fix
• ◻️ Refactoring
• ◻️ New feature
• ◻️ Change of parameter values or input data (including CES parameters)
• ◻️ Minor change (default scenarios show only small differences)
• ◻️ Fundamental change of results of default scenarios

Checklist

• I executed the automated model tests (make test) after my final commit and all tests pass (FAIL 0)
• I adjusted the reporting in remind2 if and where it was needed
• I adjusted the madrat packages (mrremind and other packages involved) for input data generation if and where it was needed
• My code follows the coding etiquette
• I explained my changes within the PR, particularly in hard-to-understand areas
• I checked that the in-code documentation is up-to-date
• I adjusted forbiddenColumnNames in readCheckScenarioConfig.R in case the PR leads to deprecated switches
• I updated the CHANGELOG.md correctly (added, changed, fixed, removed, input data/calibration)

Pull request overview

Fixes the MAgPIE→REMIND coupling for CO2 land-use change (CO2LUC) subcategories by using the correct domain so that CO2LUC subcategory values are actually transferred (instead of silently iterating over an empty intersection).

Changes:

• Update p_co2lucSub assignment to index emiMacMagpieCO2Sub over all_enty (matching its set declaration and other usages), enabling proper transfer from f_macBaseMagpie_coupling.

Thanks a lot! I guess this is a candidate for the smallest REMIND PR ever 😁
