[IMP] *_event_*: revamp event template form

This commit revamps the event template form to be similar to the event form
itself and removes unnecessary fields, purpose is to give more clarity to the
user.

It also fixes the order of the fields in the event form to be exactly
the same as in the front-end, so that the user don't get confused.
