🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Preserve the configured GROUP filter in the job lookup.

When SCF_KGRID is set, this lookup can select any matching-grid total_energy job. The helper in src/py/mat3ra/notebooks_utils/core/entity/job/api.py, Lines 189–219, does not filter by GROUP, unlike the existing property query at Line 251. If the account has a matching-grid job from another functional or application, the notebook uses its energy in the hull. Apply the configured GROUP constraint before accepting a job.

Review comment at @other/materials_designer/workflows/analyze_convex_hull.ipynb
at line 275:
Update the job lookup in the materials_with_exabyte_id flow so jobs are accepted
only when they match the configured GROUP, including when SCF_KGRID is set; do
not rely on find_job_for_material_with_property alone to enforce this filter.
