Disable biometric login after 24 hours of last password login (#971)

* Disable biometric login after 24 hours of last password login

Fixes #951

Add logic to disable biometric login if the user has not logged in via password in the last 24 hours.

* **UserSettings.kt**
  - Add `lastPasswordLoginTime` attribute to track the last password login time.

* **BiometricPrompt.kt**
  - Add logic to check `lastPasswordLoginTime` and disable biometric login if the last password login was more than 24 hours ago.
  - Add function `updateLastBiometricLoginTime` to update the last biometric login time.

* **AuthScreen.kt**
  - Add logic to reset `lastPasswordLoginTime` when users log in via password.

* **SharedPreferenceUtils.kt**
  - Add functions `updateLastBiometricLoginTime` and `updateLastPasswordLoginTime` to update the respective times in `UserSettings`.

* **ButtonBar.kt**
  - Add logic to reset `lastPasswordLoginTime` when users log in via password.
