/**
 * POST /api/accounts/wipe-all — the bulk form of /api/accounts/[id]/wipe:
 * drop every account's cached rows on every firm and rebuild them all from
 * fresh Tradovate reports. One report per account, so this takes a while on
 * big rosters; firms run in parallel, accounts within a firm sequentially
 * (that's fetchDaysTraded's own pacing against the flaky report server).
 *
 * Same destructive caveat as the single wipe: cached rows older than the
 * report's 28-day window cannot be refetched. The UI confirms first.
