Tap target for channel in recipient header is shorter than header

[gnprice]

When a channel message appears in a multi-channel narrow (like the combined feed), the recipient header has the channel name as well as topic.

Expected: Tapping anywhere in the channel part of the header should lead to the channel narrow.

Actual: Tapping directly on the text of the channel name leads to the channel narrow. But tapping slightly above or below leads instead to the topic narrow.

The problem is that the entire recipient header (including the channel area) is wrapped in a single GestureDetector that navigates to the topic narrow. We need to properly separate the gesture areas for the channel and topic sections.
