/**
 * executeSIEImport ↔ syncMappedAccounts wiring (F: customized #KONTO names
 * from Fortnox were lost on import).
 *
 * The name-resolution behavior itself is covered by account-sync.test.ts:
 * these tests assert that executeSIEImport threads the updateAccountNames
 * option through (default ON), surfaces rename counts as Swedish warnings,
 * and aborts on a fatal create error.
