feat(website): unified preview — cloud page, API & enterprise pages, use case images (#11273)

## Summary

Unified preview branch combining three feature PRs for the website
product pages.

> **Constituent PRs:** #11247, #11270, #11266

## Changes

- **Cloud page** (#11247): Add Cloud product page sections (Hero,
Reason, FAQ, AI Models, Audience, Pricing, ProductCards). Extract
`FAQSection` to `common/` and `ReasonSection` to `product/shared/` for
reuse across product pages. Add cloud-related i18n translations.
- **API & Enterprise pages** (#11270): Add API page (Hero, Steps,
Automation, Reason) and Enterprise page (Hero, Team, DataOwnership,
BYOKey, Orchestration, Reason). Add shared `CardGridSection`,
`FeatureShowcaseSection`, `CloudBannerSection`. Add all API/enterprise
i18n translations.
- **Use case images** (#11266): Replace placeholder divs with real
images in `UseCaseSection`. Add SVG blob clip-paths
(`objectBoundingBox`) and crossfade transitions on category switch. Use
`useId()` for unique clip-path IDs.

## Review Focus

- Shared component API design (`ReasonSection` slot/prop surface)
- Component placement: `common/` vs `product/shared/`
- Clip-path coordinate accuracy and crossfade transition smoothness
