Migra preferências para config global e adiciona auto-reload no player client side

---

- Extraído `Toggle` para componente compartilhado em `src/components/Toggle.tsx`;
- Preferências "Pure mode" e "Open in new tab" migradas de por-card (localStorage por stream) para configuração global (`global-prefs` no localStorage), refletidas em todos os cards simultaneamente;
- Adicionada seção "Player" no Settings com toggle "Auto-reload" e campo de intervalo em minutos; configuração lida pelo `player.html`, `/static/{id}` e `/player/{id}?mode=hls` para cobrir todos os modos de reprodução;
- Header simplificado: apenas 3 botões com ícone (Refresh, Settings, New Stream); botões de Download playlist e Sign out movidos para dentro do painel de Settings;

+# Changelog
+
+## Decap Stream v1.0.0
+
+Turn any web page into an RTMP/HLS stream. Chromium renders the page in a virtual display, ffmpeg captures it, and MediaMTX publishes it, all managed through a web UI.
+
+### What's included
+
+- **Dashboard with live thumbnails and drag-and-drop ordering**
+- **Per-stream configuration** — resolution, scale, FPS, bitrate, x264 preset/tune, GPU flag
+- **Scalable card sizes** — mini / sm / md / lg with proportional scaling across all elements
+- **Inline VNC** — inspect any stream's virtual display without leaving the UI
+- **Autologin with CDP detection** — skips login if the session is still alive on container restart
+- **Built-in HLS player** — with controls; static standalone page optimized for TV browsers (`/player.html?id=<id>`)
+- **Per-card Pure mode** — open streams as a raw `.m3u8` link or a zero-dependency `.html` page, usable in VLC or any HLS-capable player
+- **Per-card new-tab toggle** — open any action button in a new tab; settings are per-card and saved in the browser
+- **Optional UI authentication** — set `AUTH_USER` + `AUTH_PASS` to password-protect the entire UI
+- **Persistent desired state** — streams restore automatically on container restart
+
