Merge #397: UI Only Custom Datadir Display

7a8fb19 qml: UI only display datadir functionality (D33r-Gee)
b648cbb qml: added getting custom datadir for display (D33r-Gee)

Pull request description:

  This pull request builds upon #392 and introduces enhancements to display the data directory information within the UI. This functionality encompasses both default and custom data directory paths, fulfilling the UI requirements for user-defined data directory selection initiated in #273.

  Also the custom datadir is not persistent at the moment it will be once the back end wiring is added.

  As a potential follow-up enhancement, consider incorporating mechanisms for saving the data directory path. This could be achieved through:

  - Double-click functionality: Allow users to save the displayed path by simply double-clicking on it. This provides a convenient and intuitive method for desktop environments.

  - Dedicated button: For mobile use cases or scenarios where double-clicking might not be feasible, introduce a dedicated "Save Path" button. This ensures a clear and accessible action for users on various devices.
