Align pipeline runtime with data-model release

[wietzesuijker]

Summary

• lock the runtime to Python 3.12 across pyproject, tooling, and Docker so the default build.yml job keeps producing runnable main/latest images
• depend on [email protected] and lean on its dependency stack instead of duplicating xarray/zarr version ranges
• default the workflow template to the main image tag, making the staging overlay patch unnecessary
• regenerate uv.lock under the new constraints

Testing

• uv run -q pytest -q (suite currently reports "no tests ran"; coverage emits standard warning)

Follow-up

• trigger Build Docker Image after merge to refresh ghcr.io/eopf-explorer/data-pipeline:{main,latest}
• track data-model#65 (fix: sync v0.3.0 metadata data-model#65) to align eopf-geozarr packaging metadata with tag v0.3.0 (or adopt SCM-based versioning)

Spotted a few more Python 3.13 references that should be 3.12 🙈 .

I no longer have push access to this branch, but here’s a ready-to-apply patch chore-align-python-version-references.patch
that aligns remaining references with Python 3.12.
You can apply it locally with git apply chore-align-python-version-references.patch.
