feat: add user profile page and replace nav welcome text with avatar dropdown

- Replace welcome text in navigation with clickable avatar dropdown
- Add dropdown menu showing user name, email, profile link, and logout
- Create comprehensive user profile page (/profile) with:
  - Profile overview with avatar, name, email, and verification status
  - Account information section with detailed user data
  - Account activity tracking with current session status
  - Quick actions section with placeholder buttons for future features
- Add missing UI components (Card, Badge, Separator) following shadcn/ui patterns
- Use proper design tokens and destructive variant for logout action
- All components pass lint and type checking
