Feng Ruohang 5cb91e7d74 fix(decom): move a tiered version whose restored-copy removal is refused
A decommission walk removes a restored copy that is past its restore
deadline before it moves the version, as the scanner would. Since
0a546c7a7 a refused removal made filterLifecycle return the
DeleteRestored action: the walk counted the version as decommissioned
without moving it and without queuing an expiry, removeMovedVersions
then found a source copy with no retained copy and failed the key with
PreConditionFailed, the moved versions of the key stayed duplicated in
both pools, the bucket stayed queued and the decommission ended Failed;
the retry after a restart failed the same way while the refusal held.

The walk now moves the version like any other when the removal is
refused, as the release before 0a546c7a7 did: a copy past its deadline
reads as remote, so the version moves with its tier metadata and its
restore deadline through DecomTieredObject, the remote object stays,
the source copy retires with the key once the destination holds it, and
the scanner of the destination pool removes the restored copy by that
deadline. The rebalance walk never reaches this action for such a
version, which it skips as remote; its filterLifecycle now names the
same decision so neither walk counts a restored-copy expiry as a
deletion it performed.

TestDecommissionMovesRestoredCopyPastDeadline refuses the removal on
every drive of the set; before this change it failed with complete=false
failed=true, pool 0 holding the version and pool 1 nothing.
TestRebalanceLeavesRestoredCopyPastDeadline is the control for the
rebalance walk.
