fix prod : Eau2018.xls dans l'image Docker + build context racine

- backend.Dockerfile : COPY Eau2018.xls /app/ (contexte = racine projet)
- docker-compose.yml : section build: pour backend et frontend (context: ..)
- seed.py : XLS_PATH cherche d'abord /app/Eau2018.xls, fallback ../

Sans ça python seed.py échoue dans le conteneur (fichier absent)
