Make the instance console log filter discoverable

The filter was a Switch showing only the label of the mode it was already
in, so with the default of chat mode it read as a button labelled "Chat"
with no hint that a Log mode existed or that anything was being hidden.

Swap it for a Segmented control listing both Chat and Log, so the mode that
is not active is always visible, and add a tooltip describing what each one
covers.

Fixes #853
