Fix smooth scroll animation and map positioning

- Replace v-show with transform: translateY() for smooth header collapse animation
- Wrap MainNav + SubNav in fixed container with dynamic transform
- Remove sticky positioning from MainNavigation and SubNavigation
- Fix map to extend to screen edge (right-0, no rounded corners)
- Add dynamic padding-top to main for fixed header compensation
