Function apply_sat_file 

pub async fn apply_sat_file(
    infra: &InfraContext<'_>,
    token: &str,
    gitea_token: &str,
    vault_base_url: &str,
    k8s_api_url: &str,
    params: ApplySatFileParams<'_>,
) -> Result<(Vec<CfsConfigurationResponse>, Vec<Image>, Vec<BosSessionTemplate>, Vec<BosSession>), Error>

Apply a pre-rendered SAT file via the backend.

Returns the four lists of artifacts the backend produced (or would produce, in dry_run mode): CFS configurations, IMS images, BOS session templates, and BOS sessions. The handler serialises these as the JSON response body so manta apply sat-file can show them.
