fix(#74): settle on just-finished session and coherent feed health

Prefer previous_completed_session for Live settling link/poll/readiness so an
older ready default cannot short-circuit handoff; show reconnecting when phase
is disconnected even if browser SSE stays open; refresh Live visuals and add
active responsive snapshots against the Weekend shell.
