Follow-up found while reviewing the #6098 changes. A real Ledger keeps
its blockQueue syncer running after the commitSyncer is stopped, so it
still calls notifyCommit -> scheduleCommit on every block flush.

Add stopLedgerCommitSyncer, which sets deferredCommits to nil under
trackerMu so those commits take scheduleCommit's default branch and call
Done instead of leaking a WaitGroup count. This replaces the manual
drain loop in testVotersReloadFromDiskAfterOneStateProofCommitted.

Hold trackerMu for the scheduling half of triggerTrackerFlush, mirroring
notifyCommit, so the syncer cannot interleave with the manual flush.

Direct replacement for #6757. accountsWriting.Wait() raced with the
blockQueue syncer calling scheduleCommit -> accountsWriting.Add(1).
The Wait is redundant: receiving from commitSyncerClosed already means
commitSyncer has finished any in-flight commit and drained its queue, so
drop it, as #6098 did for the sibling test. Move the shutdown sequence
into a stopCommitSyncer helper used at all six call sites.

Add util.EraseFile, which overwrites a file with zeros, syncs it, and removes it. loadParticipationKeys uses it for the key files it imports, and InstallParticipationKey for its temporary copy of an uploaded key. A symbolic link, or a file with other hard links, is only removed, so a copy the operator keeps elsewhere is not destroyed. As with secure_delete, copy-on-write file systems, snapshots and flash translation layers may keep the old blocks.
