//! Redfish ManagerAccount — high-level wrapper
//!
//! Provides `Account`, an ergonomic handle over a Redfish `ManagerAccount`:
//! - Read raw data with `raw()`
//! - Update fields via `update()`, or use helpers `update_password()` and
//!   `update_user_name()`
//! - Delete the account with `delete()`; optionally disable instead of deleting
//!   when configured
//!
//! Configuration:
//! - `Config::read_patch_fn`: apply read-time JSON patches for vendor
//!   compatibility
//! - `Config::disable_account_on_delete`: make `delete()` disable the account
//!   rather than remove it
//!
//! Note: `Account` objects are created by higher-level APIs (e.g.
//! `AccountCollection`) and do not create accounts on the BMC by themselves.
//! Use the collection to create new accounts.
