fix: restore hero section with simplified video positioning

- Removed CSS contain properties that were preventing video from extending into safe area
- Implemented Vue 3 Teleport to bypass DOM containment for iOS video extension
- Video now renders at body level to properly utilize safe area insets
- Kept Safari fallbacks for env() bug workaround
