test(orders): clean statement fixtures before ingest, not after

These tests insert a Westpac statement and a `DD *DOORDASH ...` charge, and
only removed them at the end of the test — so they survived into the next run,
where `reconcileCardLeg` could match one at ingest time and resolve an order
that was meant to park `awaiting_card_statement`.

That is a real ordering bug in the fixtures regardless. It is my best
explanation for the intermittent failure in "parks an unresolvable split",
but I could not reproduce it: seeding the exact leftover row and running the
old code passed anyway. So this is hygiene with a plausible mechanism, not a
confirmed fix — if that test fails again, this was not the cause.
