/**
 * Skatteverket data shapes used by core UI (the /transactions page lives
 * in core, but renders skattekonto rows alongside bank tx). The DB table
 * `skattekonto_transactions` lives in core migrations even when the
 * skatteverket extension is disabled: the extension only owns the API
 * that populates it. Keeping these types in core means components can
 * render the table's shape without depending on the extension module.
 *
 * If skatteverket is disabled, the API returns 503 and the UI just sees
 * an empty list: the types remain valid descriptors of the schema.
