feat(story-5.1): add subscription pricing UI with Stripe checkout integration

Replace PAYG pricing tiers with subscription model (Free/Pro/Enterprise),
enable Monthly/Yearly billing toggle, wire Pro CTA to Stripe checkout with
authenticatedFetch, toast error feedback, double-click guard, checkout_url
validation, and offline graceful degradation.
