Redesign top header bar

- Remove search box from topbar (search is now on list pages)
- Clean notification bell icon
- User avatar with initials, name, and role displayed
- Divider between notifications and user section
- Logout as subtle icon button instead of red inline-styled button
- Remove inline styles, all styling via CSS classes
