failure payment cases are not handled

[SuhailAhmed2]

if there is payment failure, then we shouldt proceed with reservation
apps/reservations/src/reservations.service.ts
lines create charge doesnt checks for failure
const payemntResponse = await lastValueFrom(this.paymentService.send('create-charge', { ...createReservationDto.charge, email: user.email }))

  const newReservation = await this.reservationsRepository.create({
    ...createReservationDto,
    invoiceId: payemntResponse.id,
    userId: user._id,
    timestamp: new Date(),
    ...createReservationDto.event
  }, { session })

similarly in payemnt service

createCharge({ card, amount, email }: PaymentsCreateChargeDto) {
const paymentIntent = await this.stripe.paymentIntents.create({
amount: amount * 100,
payment_method_types: ['card'],
currency: 'usd',
});

this.notificationsClient.emit(NOTIFICATION_EVENT, {
  email,
  text: `Your payment of $${amount} has completed successfully.`,
});

return paymentIntent;

@SuhailAhmed2 you right, i haven't check this repo in a while i should've added validation & check for payment failure i guess throw some exception and rollback transaction.
