Task 13 Step 8 of phase-0 plan.
get_ap_aging → FollowupAdapter.aged_payables().
The adapter method was added alongside aged_receivables() in the previous
commit, so this is a pure tool-wrapper change. Other AP tools
(find_duplicate_bills, get_unpaid_bills, get_payment_schedule, etc.) touch
account.move / account.move.line with pure-Community filters (move_type in
(in_invoice, in_refund)) which are tri-mode safe and do not need adapter
routing.
All 9 data-adapter tests pass on westin-v19.
