Render comments associated with events as a unit rather than separately

[max-moser]

At TUW, we recently got feedback that it's slightly confusing to users that the comments that are written alongside request actions (e.g. "accept with comment") are rendered as two separate units in request detail pages.
On first glance, that takes away from the fact that they're actually one thing.

Context

When looking a the request's timeline in the API, there are several types of events; the relevant ones here being a LogEventType and a CommentEventType.
The first one marks the "accept" action being performed, the second contains the comment that was sent off along with the action.

It seems like there is currently no link between the two timeline events, which makes it hard to correlate them and also to render them together.

Perhaps we could introduce an optional link (via ID?) in the payload for comment events that tie them to their corresponding log event (if one exists)?
This could make it relatively simple for the UI to render them together as a single unit.
