Add a toast notification when a buy or sell transaction is confirmed on the Stellar network

[Chucks1093]

Summary

After a buy or sell transaction is submitted, the user receives no feedback until they refresh the page. A success toast that fires once the transaction is confirmed on Stellar — with a link to Stellar Expert — would close this feedback gap.

Scope

• Show a success toast after the buy or sell mutation settles with status confirmed
• Toast message: 'Transaction confirmed' with the truncated tx hash
• Include a 'View on Stellar Expert' link that opens the transaction on the correct network (mainnet or testnet)
• Auto-dismiss the toast after 6 seconds
• If the transaction fails show an error toast instead with the failure reason

Acceptance Criteria

• Success toast shown with truncated tx hash on confirmation
• 'View on Stellar Expert' link opens correct network URL
• Toast auto-dismisses after 6 seconds
• Error toast shown with failure reason on failed transaction
• Only one toast shown per transaction (no duplicates on re-renders)

ETA: 12 hours

I have experience working with this kind of issues.

Here's how I plan to fix it:
I can add a single success toast that appears once the transaction is confirmed, displays a truncated transaction hash with the correct Stellar Expert link for the active network, auto-dismisses after 6 seconds, and shows a clear error toast when a transaction fails, and also make sure duplicate toasts are not triggered during re-renders and add tests to cover both success and failure scenarios.

Thank you and best regards
