[FEAT] Add option to accept lower fingerprint security level

[keunes]

Hello,

Thanks Philipp for your work on Keepass2Android!

Since the update to Android 13 for Fairphone 3(+), the fingerprint sensor at the back of the device can no longer be used to log into certain apps with higher security requirements, such as some banking apps. This issue is caused by updated Android security requirements and the lack of support from [Fairphone's] fingerprint sensor manufacturer.

As a consequence, Keepass2Android (together with some other apps) is no longer accessible with the fingerprint reader.

I would like to request a new option under the 'Security' category, which would make the app accept the lower security level.

I'm not even sure this would be technically possible to change on runtime, but I'm asking because Fairphone speaks of 'apps with higher security requirements', so I assume it's something that an app declares.

this might be possible for QuickUnlock, but not for full biometric unlock (which needs to store your master key in encrypted form and therefor needs to request certain features from Android)

Thanks @PhilippC. I think that'd already help - affected users can change the setting if needed.
