Major update: Orbit site redesign

[ryanmcd118]

This PR introduces a visual refresh across the homepage and visualizer, updates navigation for consistency, and improves routing for a smoother user experience.

Changes

Homepage

• Updated hero section and typography for improved branding
• Added FAQ section with in-page anchor from navbar
• Added “Back to Top” link above footer
• Social media icons with subtle hover states

Visualizer

• Redesigned “Connect to a database” card with clearer CTAs and example URL
• Updated right-side drawer with tabs for schema and resolvers
• Drawer is resizable, collapsible, and now React-controlled
• Added tooltips on action icons
• Visual polish on table display (spacing, depth)

Navigation

• Unified structure across homepage and visualizer (logo + social icons on left, links on right)
• Homepage navbar: Visualizer, FAQ
• Visualizer navbar: Playground (external GraphQL tool)

Routing

• Renamed /data route to /visualizer
• Configured SPA-safe routing so refreshing or direct links work without 404s
