The P&L and Balance Sheet are GL-driven, but invoices/payments/bills never
posted to journal_entries (the referenced syncBillsInvoicesToLedger was never
built), so accounts with no GL activity showed $0 and were hidden.
Adds an idempotent GL posting engine (migration applied to prod), scoped to
companies whose GL is "managed" (no imported/foreign journal entries) to avoid
double-counting Bridgewater/Bent Oak:
- invoice -> Dr Accounts Receivable / Cr income (keyword-mapped, default Assessment Fees)
- payment -> Dr Undeposited Funds / Cr Accounts Receivable
- bill -> Dr expense (bill_items) / Cr Accounts Payable (+ paid leg to bank)
Auto-creates AR (1100) / AP (2000) where missing. AFTER triggers on
invoices/payments_received/bills keep the GL in sync; existing docs backfilled.
Verified debits=credits and the balance-sheet invariant holds.
