Coolify auto-creates env entries (with empty values) for every ${VAR}
reference it finds in the compose YAML at service-creation time. So
POST /services/{uuid}/envs returns 'already exists' for any env we
try to set after creation. The fix is to fall back to PATCH on that
specific error, making the helper a true upsert.
