feat(ui): add pricing section to landing page

Three honest tiers (Free / Pro £9-mo / Bring-your-own-key £3-mo) billed monthly
or yearly — never by the week (the anti-Teal positioning from
docs/remaster/RESEARCH_COMPETITORS.md), with a "Most popular" highlight and the
assistive-not-autonomous trust note. Prices are indicative placeholders for the
SaaS direction.

Verified live: pricing section + all three tiers render at "/".
