[BUG]: Settings app doesn't gracefully handle removed/moved personalization images #870

From Discord:
The "Personalize" section of a "MIDI Devices and Endpoints" card allows for the inclusion of a device image. I expected that images would be stored in db form but instead they appear to just be pointers to the actual image / folder. This requires ongoing user maintenance of images and location particularly as moving or deleting an image generates this error "An item cannot be found at the specified path (UNABLE_TO_MASK_PATH)" and the UI crashes. The image must be returned to the correct location before "Personalize will open again. Apologies if this is known, I did not find it in the github list.

The Windows property system stores only the path to personalization images, not the actual image data itself (we don't want to store large binaries in the property system). But the Settings app does not gracefully handle missing/removed images.

Consider

• Making a copy of the image in the %allusersprofile% location when the user adds it
• Better error handling around missing images
