Refactor path handling in UI components

- Removed redundant folder and file opening methods from AiTabView and FaceAiTabView.
- Introduced PathPickerField control to streamline path selection and opening functionality across multiple views.
- Updated FaceAiTabView and GeneralTabView to utilize PathPickerField for source and destination path selection.
- Created PathShellService to encapsulate logic for opening paths in the file explorer.
- Simplified XAML structure by replacing manual grid definitions with PathPickerField components.
- Removed unused namespaces and cleaned up code for better readability and maintainability.
