[Wallet] - Success message - missing

[AArolski]

Test Step: Connect Wallet to Nolus

Expected Result: The non-custodial wallet (Keplr or Leap) successfully connects to the Nolus dApp.

Actual Result: The functionality works correctly in connecting the wallet. There are error and failure messages displayed if the connection fails, but there is no success message to confirm that the wallet has been connected.

Feedback: A success message, such as “Your wallet has been successfully connected!” should be displayed after connecting to provide clear feedback to the user and verify the successful connection.
