Prevent problematic use of event types

[richardolsson]

Description

We want users to use "event types" when creating events, because it's an important aspect of the Zetkin model of being able to find people who participated in certain "types" of events down the line.

I propose that we solve this by adding a confirmation dialog when publish an event if it does not have a type, and another confirmation dialog when creating a new type, to encourage users not to create too many.

Relevant Job Stories

• When I have a lot of events in my campaign, I want to be able to filter them based on type, so that I can easily distinguish things like handing out flyers, from events like meetings
• When I’m creating a new event, I don’t want to forget adding a type, so that later when I use Smart Search or some other indirectly related feature I will find the people who attended the event
• When I’m looking for people based on previous activity, I want to exclude everyone who attended a “Member meeting” type event, so that I can focus my search on activists and not meeting attendees

Estimated size (S, M, L)

I think this is a medium sized issue because it requires both some new functionality and some design consideration. But it's not very big, because we can reuse the confirm dialog from other places.

Prerequisites

None

Requirements

• When user clicks "publish" on an event without a type, show a confirmation dialog explaining that not having a type makes it harder to search for participants in the future, and that they can add a type later.
• When user tries to create a new event type, show a confirmation dialog explaining that it's a good idea to reuse types, and only create new ones when there is not already another one that fits

Possible implementations

Use the ZUIConfirmDialogContext.
