Open attachment without saving it to storage

### Checks

- [x] I have read the Wiki, searched the open issues, and still think this is a new feature.

### Explain the problem clearly and succinctly:

I don't want to saved a sensitive attachment to storage. There is something, I think it is called an announcing through intent in Android.

### Describe the solution you'd like:

I want to just pass the file directly to the desired app.

### Describe alternatives you've considered:

_No response_

### Additional context:

_No response_

No file or test is named. Start by locating the Android attachment-opening path and the intent mechanism referenced in the issue. Done means the selected attachment is passed to the desired app without being saved to KeePassDX storage.
