Revamp footer, navbar, drone section and routes

- Replace heavy drone assets with S3-hosted video (excluded from git via .gitignore).
- Add routes for /services/web and /services/film in App.tsx.
- Rewrite Footer with framer-motion, structured social/contact/service arrays and improved responsive layout.
- Redesign DroneSection: full-bleed background video, layered panels/vignette, updated copy and styling.
- Minor content change in HeroSection (name updated to "David Bruno Vontor").
- Major Navbar refactor: improved mobile drawer with backdrop, accordion submenus, better state handling and accessibility.
- ChatSidebar: add optional onClose/onSelectChat callbacks, close button.
- ContactMe mobile CSS: tweak sizing and margins for small screens.
