sendOrder takes an optional intent. On Vest an 'open' is refused when the
account already holds the symbol, where it used to close that position as
the "entry"; the leg's exits then found nothing and its flatten opened a
fresh position with no TP or stop. A 'close' only closes or reduces, and on
a flat account is refused with NothingToCloseError, which flattenAndFail
reports as nothing to flatten instead of FLATTEN FAILED. Entries, the
extra-day round trip and flattens pass their intent; the manual order route
and the other platforms keep today's behaviour.
