//! Admin API HTTP client for heal and scanner management (rustfs/backlog#1869).
//!
//! [`AdminClient`] speaks the `/rustfs/admin/v3` surface with S3 SigV4
//! request signing (the same scheme the server's admin router authenticates),
//! so `mc`-style tooling and automation can drive heal start/query/cancel and
//! read background-heal / scanner status without hand-rolling HTTP.
//!
//! Wire structs in this module mirror the server-side shapes
//! (`rustfs/src/admin/handlers/heal.rs`, `handlers/scanner.rs`,
//! `rustfs-common/src/heal_channel.rs`), following the madmin-go model where
//! the SDK owns its own copies and round-trip tests pin the encoding. Deeply
//! nested status payloads that the server composes from runtime types are
//! carried through as `serde_json::Value` and flattened maps rather than
//! duplicated field-for-field, so the client cannot silently drift on fields
//! it never interprets.
