since few versions it show keyboard before showing fingerprint prompt

### 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:

Since few versions it briefly show keyboard before showing fingerprint prompt **and** after validating fingerprint, it's a little annoying visually.

If you try again then next times to work well because app is cached in ram or something because if you exit AND force close it from app settings then it happen again.

### Describe what you expected to happen:
no keyboard showing for half a sec

### KeePassDX version:

No source file or test is identified. Reproduce on KeePassDX 4.3.1 Libre with Android 16 QPR2 on a Pixel, including after force-closing the app, then trace the fingerprint prompt and keyboard interaction. Done means the keyboard does not briefly appear before the prompt or after fingerprint validation.
