Subject: [PATCH] feat: standardize header with AppSwitcher, SpaceSwitcher, and
 UserMenu

- Replace inline nav/Navbar with shared Header component
- Header pattern: AppSwitcher dropdown / SpaceSwitcher / actions / Sign In
- SpaceSwitcher and UserMenu work without SDK dependency
- Consistent across all r*Apps
