feat(billing): rebuild the Abonnemang page as a clean order summary (#1696)

* feat(billing): rebuild the Abonnemang page as a clean order summary

The sell view is now four outcome lines (one per paid capability), one
freeze-and-retain sentence, and price / first charge / cancellation as flat
Fönster rows above a single CTA. The decorative skyline banner and the
repeated reassurance copy are gone; each money term is stated once, where
the decision is made. Copy moves from hardcoded Swedish into the
settings_billing namespace (sv+en). BillingActions shrinks to the CTA; plan
choice lives in the price row.

* feat(billing): sell view as one number, four short benefits, one button

Second pass on the Abonnemang page: the row version still read as
cluttered. The price is now the headline (display serif, interval toggle
beside it, one exkl./inkl. line), the benefits are noun + gloss in a 2x2
grid, and the money terms are one sentence under the CTA. Legal text stays
behind the ?.

* fix(billing): list every paid capability, framed as the external connections

PAID_CAPABILITIES has seven keys, the page listed four. Add Betalningar
(stripe_payments) and Webshop (woocommerce_sync + shopify_sync) and phrase
the no-subscription line as the tier model actually works: only the external
connections pause, everything else stays.
