The tax payment file (skatt + arbetsgivaravgifter to Skatteverket BG
5050-1055) was Bankgirot LB only; banks that take pain.001 for salary,
like SEB via file communication agreements, refuse the LB .txt. The
route now accepts ?format=pain001 and generates the payment through the
supplier-payment pain.001 generator, whose Swedish giro dialect
(BG payee + SCOR OCR, Validex-validated) is exactly this payment shape.
The TaxPaymentPanel gets the same format selector as the salary
PaymentFilePanel, seeded from company_settings.preferred_payment_format,
with the missing-sender warning per format (bankgiro for LB, IBAN for
pain.001). A migration widens the tax_payment_file_format CHECK to
admit 'pain001'; bg_lb stays the default for old clients.
