Zhengchao An 6bdfdd164a refactor(ecstore,heal): return the local disk map as an owned read guard (Phase 5 disk-registry prep) (#4501)
refactor(ecstore,heal): return the local disk map as an owned read guard (Phase 5 prep)

Prerequisite for the Phase 5 disk-registry migration (backlog#939): the disk
map cannot move from the process global into the per-instance InstanceContext
while callers depend on a `'static` read guard borrowed from the global.

Change `local_disk_map_read` to return an owned guard
(`OwnedRwLockReadGuard`) via `Arc::read_owned` instead of
`RwLockReadGuard<'static, _>`:

- ecstore `runtime::sources::local_disk_map_read` now returns
  `OwnedRwLockReadGuard<..>` (holds an Arc clone of the lock), not a `'static`
  borrow of `GLOBAL_LOCAL_DISK_MAP`.
- heal's forwarding accessor and its callers (which hold the guard across
  `.await` while clearing/writing per-disk markers) keep identical behavior —
  the owned guard derefs to the same map, so iteration is unchanged.

This decouples the heal crate from the global's `'static` lifetime so a later
PR can source the map from the current instance's context. Single-instance
behavior is byte-for-byte unchanged; the same read lock is held across the same
awaits.

Verification: cargo test -p rustfs-heal (201 tests green), cargo clippy -p
rustfs-ecstore -p rustfs-heal --all-targets (clean), make pre-commit (pass).
