test(ilm): re-enable test_transition_and_restore_flows; fix test-util disk-open and restore error-path lock (rustfs/backlog#1303) The excluded test's 'missing xl.meta ... on disk2' was NOT an EC metadata-distribution issue: after a transition all four shard disks hold a fully consistent xl.meta (verified by decoding each shard). The panic came from the tier test util's open_disk, which hardcoded disk_index 0 for every disk path; LocalDisk::new validates the endpoint's (set_idx, disk_idx) against the disk's own format.json and rejected every non-slot-0 disk with InconsistentDisk, which read_transition_meta collapsed into 'missing xl.meta'. Derive the real indices from format.json instead. This also un-breaks free_version_count / wait_for_free_version_absence for non-first disks (silently 0 before). With that fixed, the test advanced to the #4877 restore self-deadlock, whose main paths #4886 already fixed. Complete that fix on the one path it missed: update_restore_metadata (the restore-failure metadata rewrite) still rebuilt copy_object options with no_lock=false and would re-acquire the object write lock the restore handler already holds. Propagate the caller's no_lock there too. Remove the test from the serial-lane exclusion list; the four remaining exclusions are unrelated known issues and stay.
