Feature-based folder structure

1. Created feature-based folder structure - Components now organized by domain feature
  2. Moved all components - 20+ files moved to new locations
  3. Updated _Imports.razor - Added all new namespace paths for global component access
  4. Updated CustomThemes.cs namespace - Changed from WebApp.Components.Layout to WebApp.Components.Shared.Layout
  5. Removed old using directives - Cleaned up Login.razor and Routes.razor
  6. Removed empty directories - Cleaned up old folder structure
