A resident should be able to setup biometric unlock feature on their app

[rakhimosip]

Proposed solution

• During the first installation and setup, the user should be able to select between passcode and bio unlock options for the app.

• If the user selects bio to unlock, an option to record biometrics is presented based on the device setting and model.

• After the biometric is recorded the app prompts the user to set a passcode to unlock. This is a fallback mechanism in case bio unlock is disabled.

• A user can enable/disable bio unlock at any point. They can use the 'Biometric unlock' option in the Profile section of the app.

Implementation Notes:

• While setting up biometric unlock the app only stores a flag that says this feature is enabled (no actual biometric data is stored in the app).

• For bio unlock the app uses Expo's Local Authentication module (https://docs.expo.dev/versions/latest/sdk/local-authentication/). It uses the same biometric configuration that the user setup for unlocking their phone.
