Refatora infraestrutura de dados, build e provisionamento de streams

---

- Movido streams.json para /app/data/streams/streams.json; volume do compose mapeado especificamente em /app/data/streams, deixando logs fora do volume persistido;
- Adicionado scripts/reprovision.mjs que regenera stream.conf e tokens VNC a partir dos templates da imagem no startup, garantindo que updates de container não exijam recriar o volume;
- Removido autologin.template.sh por-stream; substituído por scripts/autologin.sh global na imagem, com variáveis passadas via environment= no supervisor conf (com valores entre aspas
para compatibilidade com valores vazios);
- Logs de processos por stream movidos de /app/data/streams/{id}/ para /app/data/logs/{id}/;
- Adicionada função recreateStream em supervisor.ts e rota POST /api/streams/[id]/recreate; botão "Recreate" adicionado ao menu do card para limpar chrome-profile e re-provisionar;
- Adicionado auto-disparo de captureThumb no GET /api/streams/[id]/thumb quando thumb.jpg não existe e nenhuma captura está em andamento;
- Dockerfile: adicionado --mount=type=cache para /var/cache/apt e /var/lib/apt/lists (não /var/lib/apt inteiro para evitar corrupção de estado); removido --no-cache do Makefile; remoção
de pacotes limitada a curl gnupg para evitar cascata em dependências do chromium/novnc;
- Migração automática de streams.json do caminho antigo adicionada ao entrypoint.sh;
