Wizard Step 2: Implement a Refund Text Box and add info on public event page

[mariobehling]

There are potentially a number of ways we can implement a refund. For now the easiest way is to:

• add a text box where the user can add information for a refund policy in Wizard Step 2 (above privacy).

In Wizard step 2 add a helper text icon here, that shows the following info:

• "Refunds to be processed by the organizer through payment provider. Refund payments to attendees cannot be made on the eventyay platform. Please go to your payment provider, make a refund and mark the ticket as refunded in the eventyay platform."

On the public event page

• add a link that opens a pop up with the text.
• add the small link "Refund Policy" right below the bottom right of the ticket sales box
  

Future implementations can be done as outlined in #3157
