Fix z-index, conditions auth, and meal combining (#62, #63, #64)

Bug fixes:
- #62: Increase FAB button z-index from z-40 to z-50
- #63: Combine multiple meals per date+mealType in Meals tab
- #64: Make /conditions route public (no auth required)

Changes:
- FAB button now z-50 (same as modals, appears on top when scrolling)
- Meals tab groups meals by date+mealType, joins recipe names with " + "
- Conditions page moved outside protected routes group

DESIGN.md updates:
- Updated z-index hierarchy table
- Added Meals View section
- Noted conditions page is public
