Frontend implementation of platform admin flow:
- Update login.js to check for platform selection after login
- Add platform selection page (/admin/select-platform)
- Add platform context indicator in admin header
- Add is_super_admin to UserResponse schema
- Show "Super Admin" badge or platform name with switch option
Platform admins now:
1. Login normally at /admin/login
2. Get redirected to /admin/select-platform if they have multiple platforms
3. See current platform in header with option to switch
