Get Payables Summary

Returns the organization-wide net-unpaid total for a required date range, aggregated across every currently active member (a deactivated or removed member's historical payables are excluded, matching what GET /v1/members/{user_id}/payables/ would 404 on if asked about that member directly). Uses the identical per-day rate lookup and day-boundary computation as that endpoint for each member, summed into one total - not a separate calculation.

Unlike every other Payroll endpoint, this is organization-wide: no user_id path parameter, and no per-member authorization check applies - any key with access to this endpoint can see the aggregate total regardless of which specific members it would otherwise need a user_id to query individually.

Money values are in major currency units (e.g. dollars, not cents). Not paginated - returns a single aggregate object. The underlying query aggregates every day in the requested range, across every member, before summing - keep the range narrow (e.g. a pay period, not multiple years) for a large organization.
