Refactor: Centralize file and folder dialog logic

Introduces a new `Invoke-BrowseAction` helper function to consolidate the creation of file and folder selection dialogs. This change replaces scattered and repetitive `OpenFileDialog`, `SaveFileDialog`, and `ModernFolderPicker` implementations throughout the event handlers with a single, unified function call. This refactoring simplifies the event handler code, reduces duplication, and improves maintainability.
