fix(cassettes): decrement bays on an operator remediation dispense

recordTransaction only debited the cassette rows for type 'cash_out'.
An operator remediation is recorded as 'manual_dispense', so HAL's
in-memory bays went down while the persisted rows did not — and HAL
re-seeds from those rows on the next boot, so the machine came back
believing it still held bills a customer had already been handed.

A remediation against a partly-dispensed original debits again on
purpose: the original only ever debited what physically left, and this
is a second lot of bills leaving the bay.

Closes #76
