Three buckets render first on the worklist — cash_owed, partial_pending,
dispense_unreported (awaiting_dispense older than the threshold) — the
only ones whose meaning is "a customer is owed money". partial_pending
rows open the partial-dispense dialog pre-filled from the machine's
report: the fraction from dispensed_fiat_cents / fiat_amount and the
dispenser's error in the note, so the operator confirms a number the
hardware produced rather than typing one.
Machine detail shows a held-cash-out banner (code, time, reason) with a
Resume button; POST /machines/{id}/resume-cash-out records a
resume_cash_out op and publishes the window. The machine clears the hold
on receipt and the banner clears on its next state report.
