Automatically trigger the app to print a receipt

[pavlenex]

Once we complete:

• Log user in with an adequate role permission from the Server > App > SCAN QR #212
• If Lightning payment method is already configured on the Store and user logged in, do not start LDK node and isolate logic #213
• Publish BTCPay App plugin in pre-release #214
• NFC not working on the app #215

We just need to ensure printing works on the devices that will be used for the conference.

Requested during btcpay Prague for products list so the kitchen can fulfill orders easier, instant print as option

Seems we can close this one? @pavlenex

No, we can't. Automatically printing doesn't work.
