Fix issue #59 - Duplicate Orders on Checkout Page

[Arsh-S]

This PR fixes an issue where users could create multiple duplicate orders by rapidly clicking the “Place Order” button on the buyer checkout page. The submission button now correctly enters a loading/disabled state while the order request is processing.

Closes #59

Changes

• CheckoutForm.tsx

  • Added isSubmitting state to prevent repeated submissions.
  • Early return if a submission is already in progress.
  • Reset submission state when an error occurs.
  • Passed isSubmitting prop to the review form for button state control.

• ReviewOrderForm.tsx

  • Disabled Back and Place Order buttons during submission.
  • Updated button label to display “Placing Order…” for better UX feedback.
