Purpose
=======
Clean some stuff on the onboarding bars:
- Payment setting should be activated in sales settings if a payment acquirer is
activated from the sales bar, otherwise the customer can't pay with the acquirer
- No email is sent with sample documents -> sending to yourself using the chatter doesn't work...
- Select "sign online" by default
- Improve payment instructions
- Improve the default thank you message on payment acquirer accordingly (when no bank defined)
- Choose a custom payment method -> mark the step as done
- Improve buttons wording:
- Put a pointer cursor when hovering on done steps
- Fix typo : instructions -> Instructions
- Fix layout issue on tax screen
