This update adds automated testing for the Point of Sale IoT device printer functionality. Previously, when IoT devices were connected to the POS system and invoice reports, errors would occur because required services weren't available during testing. This fix ensures the feature works reliably by adding comprehensive test coverage.

Current behavior:
When an iot device is linked to the PoS and invoice report, you had an
error because action service and iot_websocket service where not
available.

Steps to reproduce:
- Install pos_iot
- Set an iot_device printer on the pos session
- Set an iot_device on the report of the invoice
- Open session, make an order and invoice it
- You get an error
