Pull request overview

Adds a dbt “marts” layer and updates the Streamlit BigQuery access layer to read from a new mart model.

• Removes unused/placeholder query functions from src/data_layer/bigquery.py and switches one query to read from a mart table.
• Introduces two new dbt mart models as passthrough views on existing intermediate models.
• Adds a marts schema YAML and bumps dbt_project.yml version (plus a new marts: config key).

marts: is added under models.projet_cc but has no value/config. In YAML this becomes null, and dbt model configs expect a mapping for subdirectories; this can lead to dbt parsing/runtime errors or silently not applying intended marts configuration. Either remove this key or give it an explicit config block (e.g., set +schema / +materialized, or at least {} if it’s meant as a placeholder).

The schema tests/documentation for mart_mensq_temperatures_sup_20deg don’t match the model it references. mart_mensq_temperatures_sup_20deg is a passthrough of int_mensq_temperatures_sup_20deg, which outputs ANNEE, Z_GEO, nb_stations, moy_nuits_ge_20 (no mois). As written, the mois not_null test will error because the column doesn’t exist, and the description claims the table contains “mois” data. Update the column list/tests/description to reflect the actual columns (or adjust the underlying model to produce mois if that’s the intent).
