2FA reset after restart the app
**Describe the bug**
2FA works once set, but when I close and reopen the app, it seems it was never set (would suggest I set a new 2FA)

**To Reproduce**
Steps to reproduce the behavior:
1. Go to 'Security and backup/Setup Cake 2FA', follow the process
2. Close the app and open it again
3. Go to 'Security and backup', 'Setup Cake 2FA' would show up again instead of 'Modify Cake 2FA'

**Platform:**
 - OS: Arch Linux x86_64
 - Cake Wallet Version: 4.21.0

**Additional context**
Installed via [AUR](https://aur.archlinux.org/packages/cake-wallet-bin).
Also,in  'Security and backup', 'Require PIN' does not work and would also reset to '10 minutes' after restart regardless of the modify.
