Description

This PR addresses issue #3654 by adding functionality to remember the last used directory for Import/Export operations.

Previously, Invoke-WPFImpex would always reset the file dialog's initial directory to the Desktop. This change modifies the ConfigDialog function to:

Check for a persistent user configuration file at %LOCALAPPDATA%\Winutil\user_config.json.
Load the LastImportExportPath from this config if it exists.
Save the newly selected directory back to this config file after a successful selection.
This improves the user experience by reducing the need to repeatedly navigate to the same folder when performing multiple import/export actions.

Link any related issues.]--> #3654

Testing

I implemented logic that:

Attempts to read LastImportExportPath from the local user config user_config.json.
Sets the InitialDirectory of the SaveFileDialog or OpenFileDialog accordingly.
Writes the parent directory of the selected file back to user_config.json upon a successful dialog result.
Handles missing config files or directories gracefully (creating them if needed).

Impact

UX: significantly improves usability for users who keep their config files in specific folders other than the Desktop.
Filesystem: Creates a lightweight JSON config file in AppData\Local.

Additional Information

The configuration is stored in a user_config.json file to allow for future expansion of persistent user settings without cluttering the main directory or registry.
