refactor(legal): extract MarketingFooter, mount on /pricing and /contact-sales

Pulls the existing /landing footer markup into
`components/common/MarketingFooter.tsx` and mounts it on PricingPage and
ContactSalesPage so the Privacy / Terms / Policies / Contact links are
reachable from every marketing surface (including the page Stripe's
reviewer spends the most time on during live-mode activation).

All three current call sites wrap in `.landing-page`, so the existing
`landing-footer` CSS — and its `--lp-*` variables — resolve without
change. Landing renders pixel-identically; Pricing and ContactSales now
match.

A JSX comment on the component documents the `.landing-page` scoping
requirement so future authors don't drop it on a non-marketing route
and see it render unstyled.
