[Feature] Persist the state of the helper text on display

**Packages**

Media

**Describe the solution you'd like**

If the user right clicks to hide the helper text on the Display window, when the app is reopened the helper text reappears. Similar to how we persist the state of the window positions, we should also persist whether or not the helper text is showing so that on reopen it will be as it was before the app closed.

**Describe alternatives you've considered**

**Additional context**

N/A

Start by locating the Media package's Display window and the existing code that persists window positions. Trace how the helper text is hidden and how settings are restored when the app reopens. Done means the helper text visibility is preserved across close and reopen, matching the previous state.
