refactor: split marketplace into homepage and storefront apps

- Remove apps/marketplace entirely
- Create apps/homepage (port 3000): landing/marketing pages (home, features, pricing, platform-ops, review, legal)
- Create apps/storefront (port 3004): vehicle browsing (explore) and renter account (dashboard, profile, notifications)
- Duplicate shared components/libs into each app
- Update homepage header nav: Home, Features, Pricing instead of Home, Explore
- Fix all /explore cross-references in homepage to point to /features
- Update docker-compose.dev.yml: new homepage and storefront services, remove marketplace
- Update docker-compose.production.yml: split into homepage (main domain) and storefront (path-based routes)
- Update Dockerfiles: EXPOSE 3004 instead of 3003
- Update root package.json scripts: homepage/storefront profiles, tests, prod scripts
- Add docker-prod-up-homepage.sh and docker-prod-up-storefront.sh, remove marketplace script
