Cash Disbursement: resolve vendor/bill for imported (Buildium GL) payments

The report only enriched app-posted (acmacc_txn) entries with vendor/bill, so
import-mode payments (buildium_gl) always showed 'No vendor on record'. It now
also pulls the vendor/bill from the register transaction linked to each GL bank
line (journal_entry_line_id), so matched imported disbursements show the vendor
(Robertson's, City of Titusville, Avria, FPL...) and bill instead of A/P.
