feat: 标准调试参数 & 克隆不立即保存

1. 新增标准调试参数
   - templates/standard_overlays/ 目录下导入 std_face_debug、
     std_test_sensitive、std_production_quiet 三个标准调试参数
   - 启动时通过 ImportStandardOverlaysFromDir 自动导入 SQLite
   - 支持 std_ 前缀只读保护，不可直接编辑/删除

2. 复制后不立即保存
   - 调试参数克隆：重定向到新建页预填数据，点击保存才入库
   - 识别模板克隆：重定向到模板编辑页预填，点击创建/进入可视化编辑才入库
   - 可视化编辑也支持 clone_source 参数，编辑保存时创建新模板

3. 简化调试参数 JSON 结构
   - 去掉 instance_overrides 层级，改为顶层 override 键
   - 运行时渲染兼容新旧两种格式
   - UI 去掉目标/目标数量字段

4. 清理死代码
   - 移除从零新建空白调试参数/模板的代码路径

 - **No `fetch()` in templates** for page data — all API calls must go through Go server-side handlers. JS is only for UI interactivity (modals, carousels, confirm dialogs).
 - **No inline `onclick` with complex quoting** — use `data-*` attributes + event delegation instead.
 - **Use `pwsh`** for PowerShell commands (v7.6.1 in PATH, not `powershell.exe`).
+- **重启服务**：统一用 `pwsh -File scripts/managerd.ps1 restart`，它会先编译、停旧进程、再启动新进程并做健康检查。不要手动 kill + build + start。
