Error toasts surfaced the raw English backend message. Added an errors namespace (fa/ar/en) keyed by error code + a useApiError() resolver that maps ApiClientError.code to the localized message (fallback to a localized generic). Wired into menu, tables, demo banner, and subscription checkout; hardened getErrorMessage so it never returns the raw backend message.

Previously the subscribe mutation had no onError handler, so any
payment initiation failure (wrong merchant ID, ZarinPal API error,
disabled payment method) would silently re-enable the button with
no user feedback. Now errors are shown below the Pay button.

Insert a factor/invoice page between plan selection and payment showing
billing-period choice, line items, and totals before redirecting to the
gateway, moving payment-method selection to where the charge happens.
