Add a live status line to the stats panel

Shows what's happening right now underneath the table (connecting,
resolving the friend, discovering targets, fetching channel history,
waiting out a jittered delay before reacting, sending a reaction,
removing a reaction during --undo, etc). Status updates are cheap
and DB-free, using the last fetched stats for re-rendering.
