Migrate to Chromium, unified VNC, thumbnails, autologin CDP detection

---

- Migrado base Docker de ubuntu:22.04 + Google Chrome para debian:bookworm-slim + Chromium
- Dockerfile refatorado com multi-stage build (node:22-alpine builder + debian runtime) e single RUN layer para imagem menor
- VNC unificado: removido novnc por stream, substituído por websockify global na porta 6080 com token-based routing
- Implementado sistema de thumbnails por stream via ffmpeg (captura do HLS) com endpoint GET/POST e atualização no card
- Autologin reescrito com detecção via Chrome DevTools Protocol: pula credenciais se já autenticado
- Adicionado padrão desiredState (running/stopped) persistido no JSON, restaurado via restore-streams.sh ao reiniciar container
- UI traduzida para inglês, formulário reorganizado com tooltips, seção avançada colapsável e GOP automático
- Player simplificado: modos HLS e HTML unificados, removido modo m3u8 separado
- Adicionado campo threads no ffmpeg; suporte a seccomp:unconfined no docker-compose
