Compare databases in detail, and export the results as files. ^ / U \ ^

### 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 would like a function to compare databases within detail, for example, like the "KeePass Vault" app. This would make it convenient for users, eliminating the need to switch between multiple apps and allowing them to do everything in one app. (The necessary information includes main data : data name, data date and time, and UUID.) It should also be possible to export the data as report files in formats such as .html, .txt, .html, and .xml.

### Describe the solution you'd like:

As explained above.

### Describe alternatives you've considered:

As explained above.

### Additional context:

I not intent to need to rush you time, take your time free. I was just only suggesting it to you consider. Thank you ❤️

The issue names no files, tests, or entry points. Start by identifying how KeePassDX currently opens and compares database files and how it exports data, then clarify the comparison fields and supported report formats before implementation; done means detailed comparisons and exports work reliably within the Android app.
