Puts spend against results for a window (since/until compare inclusively; both optional). Spend has two parts. (1) Settled credit debits from the workspace ledger, grouped by reason; in-flight reservations are excluded until they settle, credits used while Emailchaser had made the workspace's credits free are not spend and are excluded, and credits are valued at the current list price of one credit, the same per-credit price a top-up is quoted at before volume discounts, regardless of what was actually paid for them via bulk discounts or plan allowances. (2) Done-for-you order costs from each order's stored cost breakdown; orders are counted by creation time, and failed or canceled orders are excluded because their charges are unwound. Subscription (platform) fees are NOT included: the backend stores only the current subscription state, not per-window invoice history, so they cannot be attributed to a window honestly. Outcomes are sent emails, replied leads, positively-replied (interested) leads and leads marked meeting-booked in the window. costPerReply, costPerPositive and costPerMeeting divide total spend by each outcome count and are null when that count is zero. The optional campaignId narrows the OUTCOME side only - credit and order spend is workspace-level and cannot be attributed to one campaign - so per-campaign cost figures are partial attribution, not a true campaign cost.
