Privileged apps setting is obscure

### Checks - [x] I have read the Wiki, searched the open issues, and still think this is a new bug. ### Explain the problem clearly and succinctly: The passkey settings have a section Privileged apps. This shows a list of Android app IDs and their signature. The items can be highlighted by tapping on them. ### Describe what you expected to happen: I expected to be told what effect highlighting one item has. It seems highlighting enables the item and allows passkeys to work in that app. Once I unhighlight the app and try to use a Passkey, a dialog by KeePassDX appears to confirm adding the app signature again. I would also like to have an option to delete an item - without losing all settings. ### KeePassDX version: 4.5.0_beta03 ### Build: Libre ### Database version: _No response_ ### File provider (`content://` URI) _No response_ ### Android version: 16 ### Android device: _No response_ ### Additional context: I also got "Wrong signature for [...]" which I could "fix" by tapping on the entry for the specific app (i.e. Ironfox). I guess I had to disable it first so that I could add it again.
