Redesigned Medical Waiver

Shipped in 8.4. The old single-page disclaimer is now a clear, sectioned Medical Waiver: research use, not medical advice, age 18+, in-app promotions (with an explicit note that Pro members can disable promotional pushes from Profile → Notifications), AI features and what data is sent, lab insights, device access, subscriptions, and your data.

Now lives ahead of the registration step so it's the first thing a new user reads. Existing users re-accept once on this update.
