[UX] Add transaction confirmation dialog before submitting onramp/offramp orders

[kelly-musk]

Problem

Both the onramp and offramp flows submit orders with a single button click without showing a final summary confirmation. For financial transactions, best practice requires showing a clear summary of:

• Exact amount sending / receiving
• Exchange rate applied and its expiry
• Network fees
• Estimated completion time
• Destination address / bank account

And requiring explicit user confirmation before submission.

Fix

Add a confirmation dialog as the final step before calling the create-order API, surfacing all the above details and requiring the user to click 'Confirm and Pay'.

Impact

High UX + compliance — prevents accidental orders and meets financial UX standards.
