Entries of unknown outcome hold the account until settled; wipes keep their guards

Fifth review round (1eb0736):

- An entry now has three outcomes. Filled (confirmed): one-and-done is done
  for the day. Never placed: leg taken back, free to retry. Unknown (an ack
  or fill that never came back): the account — any mode — is held until a
  good sync at least 90s later shows it flat with realized P&L unchanged,
  then the leg is taken back and it may retry. Stop-after-all counts it in
  play meanwhile. This closes both the day-long bench of 52ed9c7 and the
  stacked re-entries of 1eb0736.
- Tradovate cancels an acked order whose fill didn't come within 30s (as
  TopstepX already does), so a retry can't sit beside a still-working one.
- A wipe keeps the rebuild's guards: wipeAccountData leaves the Cash History
  baseline, roll base, wipe hold, pre-wipe fund signature and the
  resolver's inferred size in account_meta; the routes forget history
  before wiping (so the stored rows are still there to read), and a wipe
  hold restored after a restart keeps its pre-wipe yardstick.
- Wipe routes take the set of typed accounts before wiping, so an account
  the resolver un-assigns mid-rebuild still counts.
