Pull request overview
This PR fixes a critical security issue where PIN-related settings (biometric authentication and PIN requirement for payments) were being backed up without the actual PIN, creating an impossible authentication state after restore. The solution removes PIN settings from the backup configuration and ensures these settings are always reset during the restore process.
Key Changes:
- Removed PIN-related settings from backup configuration to prevent authentication state mismatch
- Added automatic PIN settings reset during the restore process
- Aligned iOS behavior with existing Android implementation

Description
PIN settings (useBiometrics, requirePinForPayments) were being backed up but PIN wasn't. This created an impossible authentication state after restore
Solution: Don't backup pin settings and always reset pin settings on restore
OBS: Android already implemented this same solution
