Move registration time limit to admin settings and set standard to 15 minutes

Organizers should not have an option to set a time limit on the registration. Please move the time limit to https://eventyay.com/admin/settings and set the standard to 15 minutes. Apply the time limit for all events.

• Keep it out of wizard step 2
• Keep it out of event order forms e.g. here: https://eventyay.com/events/a315169f/tickets/order-form
