[IMP] website_event: round default datetime

Add default date_begin and date_end when creating an event.
To avoid having weird time (like 11:23) we round date_begin
to the nearest 30 minutes range and the date_end is set to
the next day of date_begin.

So for example if now is "2022-06-30 10:12" then:
date_begin = "2022-06-30 10:30" and date_end = "2022-07-01 10:30"
