Add VenueCard molecule — venue listing card for service venue select screen

- 3 component tokens (image.height, content.padding, content.gap)
- Composes Card (interactive) + Typography, consistent with ProviderCard patterns
- Hero image with role="img" aria-label for screen readers
- Meta row: location (pin icon) + capacity with "guests" suffix for clarity
- Price with "From" qualifier for transparency (split typography like ProviderCard)
- 6 Storybook stories: Default, ListLayout, EdgeCases, Responsive, OnDifferentBackgrounds, InteractiveDemo
- Critique score: 33/40 (Good) — P2 fixes applied (capacity label, price context, image a11y)
