Database not locking after screen lock

### 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 option "screen lock" is on in Settings > App settings, but after screen is locked the database is not locked.
I wait a minute then unlock the screen and can see fully unlocked database.

### Describe what you expected to happen:

The database should lock after screen lock.

### KeePassDX version:

4.3.3

### Build:

Libre

### Database version:

_No response_

### File provider (`content://` URI)

_No response_

### Android version:

_No response_

### Android device:

_No response_

### Additional context:

_No response_

No source file or test is named in the report. Start by reproducing the problem with the screen-lock option enabled, then trace how the Android app responds when the device screen locks and unlocks. Done means the database is locked before the screen is unlocked and the behavior is covered by a regression test.
