feat(desktop): implementa Convex React subscriptions para chat em tempo real

- Adiciona ConvexMachineProvider para autenticacao via machine token
- Cria hooks customizados (useMachineSessions, useMachineMessages, etc)
- Refatora ChatWidget e ChatHubWidget para usar useQuery/useMutation
- Remove polling e dependencia de Tauri events para mensagens
- Adiciona copia local dos arquivos _generated do Convex
- Remove componentes obsoletos (ChatSessionItem, ChatSessionList)

Beneficios:
- Tempo real verdadeiro via WebSocket (sem polling)
- Melhor escalabilidade e performance
- Codigo mais simples e maintivel
- Consistencia de estado entre multiplas janelas
