[Woo POS payments onboarding] Show payments IPP onboarding

[kidinov]

Closes: #12882

Description

The PR:

• Makes small UI adjustments to make the IPP onboarding error screen look ok
• Handles back icon click there
• Handles the "skip" clicks on the onboarding screens

Steps to reproduce

Try different cases available to you of the IPP onboarding not finished

• More -> POS
• Try to collect a payment or connect a reader
• Notice that onboarding screens are shown

The tests that have been performed

I tested:

• WooPAy in test mode
• Cash on delivery disabled
• WooPay disabled (with code modification as with current implementation we won't show POS at all - this is currently in the discussions)
