feat(onboarding): add onboarding v2 behind feature flag

Port onboarding v2 redesign from feat/redesign-onboarding branch as a
self-contained component, served on /onboarding behind the onboarding_v2
GrowthBook feature flag. No shared layout components modified.

- Add featureOnboardingV2 flag and mobileAppUrl constant
- Create OnboardingV2 component with hero, tag clouds, feed preview, auth flow
- Wire A/B test in onboarding page via dynamic import + feature flag
- Hide experience level in auth forms when flag is on (gated on both trigger + flag)
- Wrap feed preview with local SearchProvider/FeedLayoutProvider
