C1: getDepositTotalForInterest now filters to the interest's
depositExpectedCurrency for the auto-advance gate, so a wrong-currency
payment can no longer satisfy the deposit expectation (and mark the berth
Sold). C2: setInterestOutcome fires interest_completed only for 'won';
lost/cancelled fire a new 'deal_lost' rule that frees the berth instead of
flipping it to 'sold'. C4: add '/q/' to proxy PUBLIC_PATHS so tracked
links in outbound mail reach external recipients.
