fix(web,plugin): 前端审计修复 — 401 消除 + 统计卡片 crash + 销售漏斗 500 + antd 6 废弃 API

- API client: proactive token refresh（请求前 30s 检查过期，提前刷新避免 401）
- Plugin store: fetchPlugins promise 去重，防止 StrictMode 并发重复请求
- Home stats: 简化 useEffect 加载逻辑，修复 tagColor undefined crash
- PluginGraphPage: valueStyle → styles.content, Spin tip → description（antd 6）
- DashboardWidgets: trailColor → railColor（antd 6）
- data_service: build_scope_sql 参数索引修复（硬编码 $100 → 动态 values.len()+1）
- erp-core error: Internal 错误添加 tracing::error 日志输出
