fix(ilm): implement expire_restored delete semantics for restore expiry (#4950)

DeleteRestoredAction is supposed to demote a restored object back to its
pure transitioned state: remove only the local restored copy, strip the
x-amz-restore headers, and leave the version (and the remote tier data)
untouched. expire_transitioned_object set
opts.transition.expire_restored accordingly, but no delete path ever
read the flag, so delete_object ran an ordinary delete: on unversioned
buckets the whole object vanished and the free-version record scheduled
remote tier cleanup (tier data loss); on versioned buckets the latest
version got a spurious delete marker that replication propagated.

Route expire_restored explicitly in SetDisks::delete_object before
delete-marker resolution and replication dispatch: target the found
version with FileInfo.expire_restored=true and return early. The
FileMeta::delete_version layer already implements the semantics (strip
restore headers, keep the version, hand back the local data dir); this
wires it up.

Also fix the action matching in expire_transitioned_object (extracted
into transitioned_object_delete_opts): DeleteRestoredVersionAction
previously fell through to the full transitioned-object delete, which
removed the remote tier data of a noncurrent restored version. It now
routes through the same restored-copy cleanup with the exact version id,
matching MinIO's Action.DeleteVersioned()/DeleteRestored() dispatch.

Re-enable test_restore_chain_local_read_expiry_keeps_remote_and_allows_
re_restore in the ILM Integration (serial) lane; add unit tests pinning
the event->options routing and the filemeta expire_restored branch.

Closes rustfs/backlog#1302
