swarm-ui: move the terminal preview's state badges into a state row of the agent details table

The small preview in the detail panel keeps only the connection badge and
expand, and no longer follows the agent's state stream; the full terminal
tab keeps all its badges. The table gets a state row with the turn state, a
paused badge, and the context and billed tokens (not the model, which the
inference row shows). The preview's top padding drops to one badge row, and
the showHeaderBadges prop goes since the full-tab mount is now the only one
with badges.
