houseme cb977c4c5a fix(admin): report unreachable info members as unknown with balanced drive counts (#4607)
fix(admin): report unreachable info members as `unknown` with balanced drive counts

`GET /rustfs/admin/v3/info` synthesizes an entry for every peer, but a peer
whose properties RPC failed below the offline threshold with no cached snapshot
was reported as `initializing` with an empty drive list. That drive list being
empty meant its drives disappeared from the backend summary entirely, so
`onlineDisks + offlineDisks` no longer equaled `totalDrivesPerSet` (an operator
sees `onlineDisks: 3, offlineDisks: 0` for a 4-drive set), and `initializing` is
a misleading state for a member that has been running for hours — it reads like
a node was ejected when nothing is wrong (upstream rustfs/rustfs#4566).

Changes:
- madmin: add `ItemState::Unknown` ("unknown") and an `unknownDisks` bucket on
  `ErasureBackend` (serde `default`, so older payloads still deserialize).
- ecstore diagnostics: `get_online_offline_disks_stats` now returns a third
  `unknown` bucket instead of folding those drives into `offline`, keeping
  `online + offline + unknown == totalDrivesPerSet`.
- ecstore notification_sys: a probe miss below the failure threshold with no
  cache is now reported as `unknown` (not `initializing`) and carries the host's
  drives from the pool topology (tagged `unknown`) so the summary stays balanced;
  drive synthesis is factored into `synthesized_disks(host, endpoints, state)`,
  shared by the offline and unknown paths.

Tracked in rustfs/backlog#1049 (P1-A + P0-A).
