feat(ui): cellule agent stoppé — état explicite + reopen from scratch (#197, QA verte)

Surface UI du LayoutGrid pour un agent de cellule stoppé: - Affichage d'un état explicite quand runtimeState vaut « stopped » ou « failedStart », avec actions refresh / reopen from scratch (freshStart) et état restarting pendant la relance. - theme.css: styles .stopped-agent-cell (boutons primary/secondary, états disabled). Consomme le contrat runtime issu de #196 (AgentRuntimeState stopped/failedStart, freshStart) déjà présent dans develop; aucune modification runtime ici. Tests QA verts: LayoutGrid.test.tsx, LayoutGrid.chat.test.tsx (rejoué aussi: agent_lifecycle launch_fresh_start_ignores_existing_conversation_id_and_mints_new_one).
