[Bug]: Magic environment variables don't generate passwords

[tobidope]

Error Message and Logs

Steps to Reproduce

1. Add docker-compose.yaml with magic environment variables

services:
  miniflux:
    image: "miniflux/miniflux:latest"
    expose:
      - "8080"
    depends_on:
      db:
        condition: service_healthy
    environment:
      - "DATABASE_URL=postgres://miniflux:${SERVICE_PASSWORD_DB}@db/miniflux?sslmode=disable"
      - ADMIN_USERNAME=admin
      - ADMIN_PASSWORD=${SERVICE_PASSWORD_MINIFLUX}
  db:
    image: "postgres:17-alpine"
    environment:
      - POSTGRES_USER=miniflux
      - POSTGRES_PASSWORD=${SERVICE_PASSWORD_DB}
      - POSTGRES_DB=miniflux
    volumes:
      - "miniflux-db:/var/lib/postgresql/data"
volumes:
  miniflux-db:

2. Expect environment variables to be filled with a random password like documented in https://coolify.io/docs/knowledge-base/docker/compose#coolifys-magic-environment-variables
3. Variables are empty, the database doesn't start
