Add integration test for the buy flow showing a pending state indicator while the transaction is in flight

[Chucks1093]

Summary

Between the moment a user submits a buy and the moment it confirms on-chain, the trade panel should communicate that a transaction is in progress. An integration test should confirm a pending indicator is visible during this window and disappears after confirmation.

Scope

• Connect a mock wallet and submit a buy transaction
• Assert a pending indicator (spinner or disabled state with loading text) is visible before confirmation arrives
• Resolve the transaction as confirmed
• Assert the pending indicator is gone and the success toast is visible
• Assert the submit button is re-enabled after confirmation

Acceptance Criteria

• Pending indicator visible immediately after submission
• Pending indicator absent after confirmation
• Success toast visible after confirmation
• Submit button re-enabled after confirmation

ETA: 12 hours
