* fix(ecstore): bound decommission capacity gate waits
* fix(ecstore): keep rebalance meta save lock errors retryable
The rebalance metadata retry policy only retries when the source chain still
carries the typed lock error, but resolve_rebalance_meta_save_result collapsed
every failure into a plain string. A transient rebalance.bin write-lock timeout
therefore bypassed retry_rebalance_metadata_access entirely and surfaced as a
hard failure of the periodic and terminal rebalance metadata saves.
Wrap the failure with the data-movement stage context instead, which keeps the
original lock error reachable through rebalance_error_source so the existing
transient lock policy applies. The rendered message is unchanged.
Add a regression test that feeds the wrapped meta save lock timeout through the
retry helper and asserts the retry engages.
* chore(ecstore): refresh error format ratchet baseline
Removing the string-wrapped meta save failure drops one `::other(format!`
call site in the rebalance worker, so the shrink-only baseline must be
regenerated in the same change.
