fix: Add .env file check and environment variables for docker compose

- Fix 'argument of type bool is not iterable' error in image pull task
- Check if .env file exists before docker compose up
- Create minimal .env file if it doesn't exist with required variables
- Load secrets from vault file if available
- Set database and MinIO variables from vault or defaults
- Pass environment variables to docker compose command
- Fixes missing MINIO_ROOT_USER, DB_USERNAME, DB_PASSWORD, SECRETS_DIR errors
