Better handling of update errors

[noahmaranesi]

Hi!

Went to update and app and put it in the background. A notification came up saying that Latest was prevented from making app changes (some native security measure on macOS). I clicked the notification but it disappeared and didn't open up System Settings or anything (very helpful Apple 🙄)

Now in Latest, attempting to update the app shows the following message:

---

To fix:

System Settings.app → Privacy & Security → App Management → Latest → Enable

If Latest.app is not found on that list already, clicking the + and selecting Latest.app will add it.
