Zhengchao An 5594b18912 fix(ecstore): make delete_volume non-recursive by default to prevent bucket-heal wipe (backlog#799 B1) (#4339 )

* fix(ecstore): make delete_volume non-recursive by default to prevent bucket-heal wipe (backlog#799 B1)

`delete_volume` unconditionally `remove_dir_all`'d the whole bucket tree, and the
bucket-heal "remove" branch called it fire-and-forget on every local disk. A
mis-classified "dangling" bucket (or a non-force S3 DeleteBucket on a populated
bucket) was therefore recursively wiped — a potential whole-bucket data loss.
The `VolumeNotEmpty` -> recreate/`BucketNotEmpty` handling already present in
both delete_bucket paths was dead code because the primitive never refused.

Add an explicit `force_delete` flag to `DiskAPI::delete_volume` and default the
non-force path to a non-recursive `remove_dir` (rmdir), which fails atomically
with `VolumeNotEmpty` if the bucket still holds any object data. Only an explicit
force delete (S3 force bucket delete) removes recursively. Mirrors MinIO's
`xlStorage.DeleteVol` (`Remove` vs `RemoveAll`).

- Trait + all impls (local behavior, dispatch, disk_store, remote RPC) take the
  flag; the gRPC `DeleteVolumeRequest` gains a `force` field (proto3 default
  false → old peers get the safe non-recursive behavior on rolling upgrade).
- Heal remove branch passes `false` and no longer discards the result: a
  `VolumeNotEmpty` refusal is logged (the bucket is not dangling) instead of
  wiping data.
- Both `delete_bucket` paths pass `opts.force`, activating the previously-dead
  `VolumeNotEmpty` -> `BucketNotEmpty`/recreate handling (correct S3 semantics).

Adds a regression test: non-force delete of a non-empty bucket returns
VolumeNotEmpty and preserves the data; force delete removes it.

Design converged by two independent expert reviews (MinIO-fidelity +
defense-in-depth) referencing MinIO xl-storage.go. Refs backlog#799 (B1),
issue rustfs/backlog#850. The safety expert's deeper hardening (typed
capability instead of a bool, trash-instead-of-in-place for force, quorum
re-verification of dangling) is noted on #850 as follow-up.

* fix(ecstore): reword 'mis-classified' -> 'misclassified' to satisfy typos (backlog#799 B1)

* fix(rustfs): thread force_delete through StorageDiskRpcExt::delete_volume + test literal (backlog#799 B1)
