feat: wire real FoodShot Airtable photos into all 6 hero concepts

Pulled 6 before/after pairs from Airtable (appLTdg20j8oQfUsP):
- Culinary Dropout, Tokyo Hana, El Jefe, CAPO PIZZA, Mega Burgers, Roost

All gradient placeholders replaced with actual restaurant photos:
- 3A: Real before/after in phone mockups
- 3B: Real photo falls into portal, enhanced version emerges
- 3C: Real photo enters factory, enhanced output on monitor
- 4A: Rotating gallery of all 6 restaurants with revenue indicators
- 4B: Before/after thumbnail grid next to food-themed robot
- 4C: Full before/after image slider with restaurant selector
