+-- Auto-create record-only bills for no-bill vendor payments in IMPORT-MODE companies.
+--
+-- Buildium often records a vendor payment as a direct check (Dr Expense / Cr Bank)
+-- with no Bill behind it. For import-mode companies (gl_auto_post=false) the GL is
+-- the Buildium pull, and post_bill_gl no-ops, so a bill is a RECORD ONLY — creating
+-- one for such a payment surfaces it on the Bills page WITHOUT touching the GL (the
+-- expense is already booked once via the check). This makes A/P / vendor history
+-- complete without any double-count.
+--
+-- A "no-bill vendor payment" = a buildium_gl journal entry that: looks like a check
+-- /payment (description), debits >=1 expense account, credits >=1 asset account (the
+-- bank), and has NO accounts-payable line. Idempotent: skips entries that already
+-- have an acmacc_autobill_nobill bill. Vendor is resolved from the payee (text after
+-- the last "·" in the description) by exact name match; unmatched => bill with no
+-- vendor (still correct on the GL, fixable later). Safe to call after every GL pull.
