feat: redesign homepage, add global footer, fix carousel font

Homepage: restored original v0 design, replaced lorem ipsum with real service descriptions, added BusinessHours (Opening Hours) section, alternating bg-gray-50 section backgrounds. Layout: added global sticky footer (hidden on /admin/schedule, /account, and ?format=pdf pages), wrapped content in min-h-screen flex layout. PortfolioCarousel: set heading to Playfair Display.
