What it solves

How this PR fixes it

• Displays the button to open the safe list sidebar if there are owned safes detected

How to test it

1. Open the welcome page
2. No button should be visible when not connected and there are no added safes
3. Connect with a wallet that owns safes
4. Observe the button appears and displays the number of owned safes + added safes

The total number is not 100% accurate as there can be duplications between owned and added safes. Imo not a big issue though since thats the number of safes the user can see in the sidebar.
