Enhances super user experience with Castle wallet

Simplifies the user experience for super users by automatically using the Castle wallet for transactions, removing the need to configure a separate user wallet.

This change streamlines the workflow for super users by:
- Automatically assigning the Castle wallet to super users
- Hiding the user wallet configuration options in the UI
- Reloading user wallet settings to reflect the Castle wallet
