Create a `Waiting for a payment` page

[jakubtobiasz]

Currently, when a BLIK code is provided, we are redirected directly to the order's show page, so we see a list of available payment methods. Not handling the processing payment state is what causes it. This task aims to provide a Waiting for a payment page, which will be displayed for every payment that is in processing.

Small wins 🏆

• [x] After providing a BLIK token, the customer is redirected to the waiting for a payment page
• [x] This page is refreshed automatically, so the customer can just wait for the status update
• [x] Once a payment becomes completed, this page should redirect the customer to the thank you page
• [ ] After <param> minutes, if the payment is not completed, the customer should be redirected to a payment failure page
