test: dispense outcome capture — handler transitions, payment gate, resume op, hold mirror

Twenty tests in the project's style (asyncio.run, monkeypatched crud, no
DB): confirmed → pending + distribution; nothing out → cash_owed; some
out → partial_pending with nothing spawned; already-captured recorded
not moved; identical resend acked without a row; report-before-payment
stored unlinked and adopted when the payment lands; remediation moves
the owed settlement; a remediation that did not confirm leaves it;
unpaired sender / malformed body refused. The payment gate: cash_out →
awaiting_dispense with no distribution, cash_in unchanged. The
resume_cash_out op's position rule and wire shape, the worklist model's
new buckets, and the state-document hold mirror set-and-clear. The
existing nulls-never-reach-the-wire test learns the machine-wide op.
