[Feature]: Auto-start Face ID unlock when app opens

[piotr-iohk]

Problem or use case

When Bitkit for iOS opens into the locked state and Face ID is enabled, the user currently needs to manually tap the Face ID button to trigger biometric authentication.

This adds an avoidable interaction on every locked app access. If the user already chose Face ID and enabled the option to lock the app at startup, the expected flow is that Bitkit immediately starts the Face ID scan when the locked screen appears.

Proposed solution

When Face ID unlock is enabled and Bitkit opens locked, initiate the Face ID prompt automatically without requiring the user to tap the Face ID button.
