Managing invoices in BTCPay (troubleshooting an invoice)

[pavlenex]

We really should make a video explaining invoice management and troubleshooting. There are so many different situations that can happen during and after the payment, and our video should be a one-to stop for merchants to watch so that they could know how to react based on certain situation.

This needs to be well-planned video, as it's very important subject that I think we failed to see the importance of documenting visually.

@petzsch is gonna have a look at getting the initial structure and possibly footage for this.
