Transport improvements for 2026-W04

[khaeru]

#447 ← previous PR | following PR → #497

MESSAGEix-Transport itself:

• Switch non-LDV technologies to the same stock representation used for LDVs.
• Reporting
  • Expand reporting output to include stock and sales of non-LDV vehicles.
  • Adjust reporting labels for non-LDV technologies.
• Transfer placeholder data for parameters of non-LDV vehicles from SharePoint folder. Next PR.

Materials-Transport integration:

• Add missing units "Mt / Mv" to platform/build.
• Direct output_cap_new to level=end_of_life.
• Add a ratio between input_cap_new and output_cap_ret, representing a portion of the materials for each vehicle type that is non-recyclable.
  • Currently this is a fixed, scalar value.
• Expand transport reporting with material inflows, outflows per technology and technology groups. Next PR.

For CircEUlar:

• Add a distinct workflow to build, solve, and report these scenarios.
  • CLI entry-point for this workflow.
  • Reuse transport workflow steps.
• Complete iiasa/message_data#622.
• Invoke the workflow via CI or on UniCC, like the MESSAGEix-Transport workflow. Next PR.

For ScenarioMIP:

• Update base scenario identifiers to v6.5.
• Retrieve and store price trajectories for 17 scenarios (below)
• Add these to CL_TRANSPORT_SCENARIO, bump version.

How to review

• Read the diff.
• Note that the CI checks all pass.

PR checklist

• Continuous integration checks all ✅
• Add or expand tests; coverage checks both ✅
• Add, expand, or update documentation.
• Update doc/whatsnew.

The one failing job is due to network errors accessing a remote server:

ERROR message_ix_models/tests/tools/test_wb.py::test_get_income_group_codelist
ERROR message_ix_models/tests/tools/test_wb.py::test_assign_income_groups[R12-population-None]
ERROR message_ix_models/tests/tools/test_wb.py::test_assign_income_groups[R12-count-None]
ERROR message_ix_models/tests/tools/test_wb.py::test_assign_income_groups[R12-population-0] - requests.exceptions.ConnectionError: HTTPSConnectionPool(host='api.worldbank.org', port=443): Max retries exceeded with url: /v2/sdmx/rest/codelist/WB/ (Caused by NameResolutionError("HTTPSConnection(host='api.worldbank.org', port=443): Failed to resolve 'api.worldbank.org' ([Errno 8] nodename nor servname provided, or not known)"))

Since these are transient and don't affect other jobs, I'll merge without waiting for this job to re-run.
