Fix bazaar vendor QR code generation and payment status update

[Copilot]

Bazaar vendors were not receiving QR codes after payment, and paymentStatus remained 'pending' instead of updating to 'paid'. This worked correctly for platform booth vendors but was missing for bazaar vendors.

Changes

Backend/controllers/bazaarVendorApplicationsController.js

Added QR code generation and email delivery to updateBazaarVendorApplication() when payment completes:

• Track previous status to detect status: 'awaiting_payment' → 'accepted' transitions
• Update paymentStatus: 'pending' → 'paid' in database
• Generate QR codes for each attendee with application metadata
• Send individual QR code emails to attendees
• Send consolidated QR code email to vendor

Implementation mirrors existing platform booth logic in vendorApplicationsController.js.

// Added status change detection
const previousStatus = doc.status;
// ... update logic ...
if (refreshed.status === 'accepted' && previousStatus !== 'accepted') {
  await BazaarVendorApplication.findByIdAndUpdate(id, { paymentStatus: 'paid' });
  
  // Generate and send QR codes for each attendee
  const qrCodes = [];
  for (let i = 0; i < refreshed.attendeeNames.length; i++) {
    const qrData = {
      applicationId: refreshed._id.toString(),
      applicationType: 'bazaar',
      vendorId: refreshed.vendorId.toString(),
      attendeeName: refreshed.attendeeNames[i],
      // ...
    };
    const qrCodeDataUrl = await QRCode.toDataURL(JSON.stringify(qrData));
    qrCodes.push({ attendeeName, attendeeEmail, qrCodeDataUrl, qrData });
    
    // Send individual email to attendee
    await sendAttendeeQRCodeEmail(attendeeEmail, attendeeName, qrCodeDataUrl, ...);
  }
  
  // Send all QR codes to vendor
  await sendVendorQRCodesEmail(vendor.email, vendor.companyName, qrCodes, ...);
}

Error handling ensures payment succeeds even if email delivery fails.

Original prompt

whenever i pay for a bazaar as a vendor, i should be getting qr codes alongside the receipt each in a seperate email, similar to how it is implemented for platform booths but this doesnt work at all. i only get the receipts and when i checked the database the paymentstatus remains pending after paying unlike platform booth which becomes paid so can you fix this issue

I understand. Could you please clarify what specifically didn't work? This will help me identify the exact issue:

1. Did you receive the payment receipt email?
2. Did you receive any QR code emails (either to vendor or attendees)?
3. When you check the database, is the status field 'accepted' or still 'awaiting_payment'?
4. Is the paymentStatus field 'paid' or still 'pending'?
5. Did the payment complete successfully in Stripe/Wallet?

Any error messages from the browser console or server logs would also be helpful.

@copilot check the entire registration functionality present in mo/ali branch in the student dashboard upcoming events section (follow the entire flow and check all the api calls and the things that happen in the backend) and do exactly as it is in this branch. at this moment whenever i press on register nothing happens

I don't have access to the mo/ali branch in this environment. Could you clarify:

1. Are you referring to bazaar vendor registration (vendors applying for booths) or student event registration (students registering for events)?

2. When you say "whenever i press on register nothing happens" - which specific page/component are you on? Is it:

   • Vendor applying for a bazaar booth?
   • Student registering for a bazaar event?
   • Something else?

3. What should happen when you click register? Should it:

   • Open a payment modal?
   • Create an application?
   • Register directly?

Alternatively, could you describe or share the registration flow from the mo/ali branch so I can replicate it here?
