0048455: JIRA 2615 - WebUSB - can't print a receipt and POS blocked if an image can't be downloaded

Description

When printing a receipt using webusb
If an image to print can't be downloaded from the central server (server unavailable or file not found)
Then the receipt is not printed and the POS is blocked (can't close the current order)

In any case this should block the POS.
If an image is not available, then the receipt should be printed without it anyway.

Another point of improvement;

download the image that can be used on ticket when opening the POS and store them in indexdb or local storage (see also https://openbravo.atlassian.net/browse/FLUN-736 [^])
the image are then always available to be printed on the POS

Steps To Reproduce

Use a template of receipt that contains image to download from the central server.
(make sure the image is not in cache)

Connect to POS2
Disconnect network
Create an order and chose to print the receipt

=> KO, an error is triggered because the image is not available, the receipt is not printed and the order is blocked on the payment page
