Fix full menu modal scroll behavior

- Remove overflow-y scroll from .full-menu-modal to prevent entire modal from scrolling
- Add overflow-y: hidden to header, top-nav, keywords sections to block vertical scroll
- Ensure only .full-menu-list area is scrollable
- Fix issue where menu content was scrolling through header area
