style(infra): reflow un commentaire du compose Airflow à 100 colonnes

docs(architecture): décrit les composants Airflow 3
Quatre services au lieu de trois (api-server, dag-processor), le secret JWT partagé et le choix du FabAuthManager. Le Python 3.12 d'etl/airflow est celui de l'image retenue, plus une limite d'Airflow.

Le webserver devient l'api-server (healthcheck /api/v2/monitor/health) et le dag-processor est un service à part : depuis Airflow 3 le scheduler ne parse plus les DAGs. Les tâches passent par l'Execution API de l'api-server avec un jeton signé par AIRFLOW_JWT_SECRET, nouveau secret du .env partagé entre conteneurs. AIRFLOW_WEBSERVER_SECRET_KEY devient AIRFLOW_API_SECRET_KEY. airflow-init refuse toujours de démarrer si l'un des secrets manque. FabAuthManager explicite : le SimpleAuthManager par défaut ne sait pas créer le compte admin que airflow-init pose via _AIRFLOW_WWW_USER_*.
