Steps used to test these changes

Stability is a top priority for Files and all changes are required to go through testing before being merged into the repo. Please include a list of steps that you used to test this PR.

1. Opened Files
2. Confirmed that the application starts without a TypeInitializationException related to Win32Helper.
3. Navigated to Control Panel and Control Panel Category View to ensure they load correctly.

Fixes FILES-APP-4NW. The issue was that: Missing Vanara.Windows.Shell.Common assembly causes fatal TypeInitializationException during eager static initialization of Win32Helper.

• Use Lazy to initialize ShellFolder instances for Control Panel and Control Panel Category View.
• This defers the initialization of these objects until they are actually needed, potentially improving startup performance.
