Code refactoring and general improvements

[HotCakeX]

• Refactored lots of codes to be more optimized and use less lines of code.
• Improved the icons in the supplemental policy creation and policy creation pages.
• The Create policy page's deploy buttons are now consistent with the rest of the deploy buttons in the app.
• Improved consistency in the codebase and UI elements.
• Improved log messages.
• Removed 2 unused methods.
• Reduced the number of empty lines in XAML and C# files.
• Removed unused declarations in the XAML pages.
• Improved the comments in the code to be clearer and more accurate.
• Added sidebar support to the PFN based and Strict kernel-mode supplemental policy creation sections.
• Removed the static color for text highlights in flyout text boxes. The colors are now dynamically set based on the Windows accent color.
• The "Get Configuration" button in the Settings page now automatically expands the section to make the configurations visible, reducing extra clicks/taps needed.

• The log message should be moved after the file write operation to ensure accuracy.

Logger.Write("The UserConfigurations.json file has been updated successfully.");

AppControl Manager/CustomUIElements/SigningDetailsDialog.xaml.cs:282

• Consider adding a null check for the 'message' parameter to avoid potential issues.
