Fix(pipeline): optimize docker build, fix zip structure, and update UI

- Docker:
  - Explicitly install pixi environments (digger, pipeline, webbackend) during build to prevent runtime network/DNS failures.
  - Optimize pnpm config (copy method) to fix EAGAIN errors.
- Backend:
  - Refactor ZIP bundling: use flat semantic directories (1_Toxin_Mining, etc.).
  - Fix "nested zip" issue by cleaning existing archives before bundling.
  - Exclude raw 'context' directory from final download.
- Frontend:
  - Update TutorialView documentation to match new result structure.
  - Improve TaskMonitor progress bar precision (1 decimal place).
  - Update i18n (en/zh) for new file descriptions.

+### Building the Image Manually
+
+To build the image manually, ensure you set the correct build context so that `pixi.toml` can be found.
+
+```bash
+# Option 1: From project root (specifying context)
+docker build \
+    --network=host \
+    -f web/zly/docker/dockerfiles/Dockerfile.traefik \
+    -t hotwa/bttoxin-app:latest \
+    web/zly
+
+# Option 2: Enter directory first
+cd web/zly
+docker build \
+    --network=host \
+    -f docker/dockerfiles/Dockerfile.traefik \
+    -t hotwa/bttoxin-app:latest \
+    .
+```
