The per-account wipe works one account at a time; when every account is
carrying stale cached rows (the pre-roll dates again), that's a lot of
clicking. POST /api/accounts/wipe-all drops the cached rows for every
account on every firm and rebuilds them all from fresh reports — firms
in parallel, accounts within a firm at fetchDaysTraded's own pacing.
The toolbar button confirms inline with the same 28-day-window warning.
