feat: add Snehalata to Aura own-products showcase

- Add Snehalata (AI clothing ecosystem) to ownProducts in data.jsx
- Redesign FlagshipProduct section: single-product -> scalable multi-product grid
- New OwnProductCard component: color-coded per product, features, stack, CTAs
- Section header updated to be generic (not GlamourTouch-specific)
- Bottom nudge: 'Want Aura to build your product? From $499'
- Both snehalata.com and glamourstouch.com now showcased side by side
