Improve view Signature field

### 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:

Currently, the AndroidApp Signature view is displayed as a standard customized view.

### Describe the solution you'd like:

It would be more visual to display it as a single view with the AndroidApp that contains the application ID.
This will be done during refactoring in Compose.

Locate the current AndroidApp Signature view and the Compose refactoring entry point, since no file or test is named. Compare the existing customized view with the requested single view containing the application ID; done means the Signature view is represented in that visual form during the Compose refactor.
