Function managed_businesses 

pub fn managed_businesses(
    adapter: &dyn DatabaseOperations,
    config: &DbBackendConfig,
    schema: &AppSchema,
    user_id: i64,
    limit: usize,
) -> Result<Vec<ManagedBusiness>, DatabaseError>

Lists active managed businesses in creation order using only generic queries. Membership and tenant reads are bounded and fail closed on overflow; only authorized business IDs reach the final ordered, limited query. Names never determine presentation order, including when a business is renamed.
