ci(docker): 并行构建 + GHA 层缓存，大幅缩短镜像构建时间
- docker-image.yml 拆分 backend/web 并行 job，互不排队 - 两个 workflow 的 build-push-action 全部接入 Buildx GHA 缓存 （scope=backend/web 跨 workflow 共享，首次冷启动后复用 apt/pip/restore/npm 层） - 后端 Dockerfile 移除 build+publish 双重编译，改为单次 dotnet publish --no-restore - 版本提取由 pwsh 冷启动(约16s)改为 bash(约1s) - .dockerignore 排除 docs/tests/scripts 等非构建目录， 避免其变动打碎 COPY . . 缓存层
