a restart mid-sync stranded accounts at syncing or queued forever

getAllSyncedAccounts only picks up status = synced, so an account whose sidecar
process died between marking it syncing/queued and clearing that status again
dropped out of the cron and the IDLE watcher silently, with no error to explain
why background sync had stopped. Reset both on startup instead: the job runner
is in-memory, so neither state can be genuinely in flight in a fresh process.
