agent page: consolidate alive/thinking/paused into one status badge

mara, #3757: fold the separate alive badge into the turn-state badge,
with pause/resume + cancel-turn moved into its dropdown. Cancel-turn is
click-again-to-confirm, not a modal.

model/effort/ctx/cost stay as separate badges — not asked to fold
those in too.
