fix: ensure mobile menu and language dropdown appear in front of hero banner video (raised z-indexes for overlays)

- Navbar: z-[999]
- Mobile menu container/panel: z-[1000]/z-[1001]
- Cart drawer: z-[980]/z-[990]
- LanguageSwitcher dropdown/backdrop: z-[1010]/z-[1020]
- Updated comments
- Mobile menu (incl. when clicking language inside it) now reliably stacks above the mobile banner video and other content.
