Add ability to filter main Event Definitions page list by enabled/disabled status

[danotorrey]

The Event Definitions page shows a status column (enabled/disabled) that you can click to toggle state, but there's no way to filter the list by status (even within Search field). On instances with a lot of event definitions, it'd be useful to narrow down to just the enabled ones (or just the disabled ones) without scanning the whole list.

The backend already defines status as an EntityAttribute on EventDefinitionsResource, but it isn't registered in SEARCH_FIELD_MAPPING, and the frontend doesn't wire it up as a filter. Tags got a similar treatment recently via a custom filter component (EventDefinitionTagsFilter.tsx), so this would follow that pattern.

Notes

• Backend: add status to SEARCH_FIELD_MAPPING in EventDefinitionsResource.java
• Frontend: register a filter for the status attribute — either the generic boolean dropdown if PaginatedEntityTable supports it, or a small custom component
• The underlying data is already there (EventDefinition.state is an ENABLED/DISABLED enum), so this appears to be UI/wiring only

Maybe worth noting that we also have #17437, which this issue partly duplicates (i.e. the filter feature).

Looks like this is implemented as of #26063 ?

@ryan-carroll-graylog can you confirm we'll see that shipped starting with >= 7.2?

The only changelog file i can find is in master so i assume this is the case.

[ryan-carroll-graylog]

As it stands yeah it would be 7.2+ @drewmiranda-gl ,
unless there are plans for a backport @AntonEbel ?

[AntonEbel]

I don't think a backport is planned, right @tellistone?

[tellistone]

No backport planned, its not a bug fix
