Final batch of code conversions — 12 l10n_ca accounts that we kept active
because they have historical postings. Renaming preserves all FK
references (account_id stays the same), just changes the displayed code.
112005 Scotia Current 9309 -> 1010 (primary operating bank)
112004 BMO -> 1030
112007 RBC -> 1040
112008 Scotia Credit Card 5890 -> 1070
112006 RBC VISA -> 1071
112002 Outstanding Receipts -> 1080 (in-transit receipts)
112003 Outstanding Payments -> 1081 (in-transit payments)
112001 Bank Suspense Account -> 1090
115100 Customers Account -> 1100 (AR control)
118310 HST receivable - 13% -> 1215 (legacy HST receivable, near new 1210 ITC)
211100 Vendors Account -> 2010 (AP control)
213310 HST to pay - 13% -> 2115 (legacy HST collected, near new 2110)
Verification: 140/140 active accounts now use 4-digit codes. All four
end-to-end test invoices still post correctly.
