Task 13 Step 7 of phase-0 plan.
Routes the AR tools through the FollowupAdapter so they work identically on
fusion-native, Enterprise, and pure Community installs:
- get_ar_aging → FollowupAdapter.aged_receivables()
- get_overdue_invoices → FollowupAdapter.overdue_invoices()
- send_followup → FollowupAdapter.send_followup()
- get_followup_report → FollowupAdapter.followup_report_html()
FollowupAdapter extended:
- overdue_invoices() now includes partner_email, partner_phone and
amount_total so the tool wrapper can render its richer response.
- aged_receivables() and aged_payables() new shared-implementation method
_aged_buckets() produces the 5-bucket aging shape the AR/AP tools emit.
- followup_report_html() and send_followup() isolate the Enterprise
account.followup.report / partner.execute_followup calls; Community mode
returns a graceful error dict.
Pure-Community tools in accounts_receivable.py (get_partner_balance,
reconcile_payment_to_invoice, get_unmatched_payments) unchanged — they touch
account.move / account.move.line directly which is tri-mode safe.
3 new data-adapter tests added (total: 9; all passing on westin-v19).
