Function handle_sop_rename 

pub async fn handle_sop_rename(

    headers: HeaderMap,
    __arg2: Path<String>,
    __arg3: Json<SopRenameBody>,
) -> Response<Body>

Move a SOP to a new name. PUT /api/sops/{name} can only ever overwrite the SOP named in its own URL, so a name change is its own collision-checked operation rather than a save with a different name in the body.
