fix: implement GPT's iOS notch video extension solution

- Added html/body reset styles (margin:0, padding:0, background:#000)
- Removed ALL overflow:hidden from html, body, hero-voyage, and hero-video-container
- Changed hero-voyage to use overflow:clip (prevents scrollbars while allowing extension)
- Fixed video container positioning:
  - Changed from absolute to fixed positioning
  - Added top: calc(-1 * env(safe-area-inset-top)) to pull video into notch
  - Height: calc(100lvh + env(safe-area-inset-top)) with 100vh fallback
  - Set z-index: -1 to place behind all content
- Updated mobile styles to match desktop implementation
- Removed overflow-x:hidden from all parent elements

This follows GPT's exact checklist for iOS notch video extension.
