fix(web): 自动刷新保留 K 线视窗；威科夫与图表增量更新

自动刷新改用 tail update 与 scrollToPosition 恢复视窗，避免 setData 后跳到最右；拆分 chart_tv 模块并扩展 analyze/recent API。同步威科夫分析、pipeline 增量构建及相关策略与配置。 Co-authored-by: Cursor <cursoragent@cursor.com>

+"""增量更新：新K只追加 KLU/KLC，笔与笔中枢在当前列表上重算。
+
+不改 init_TF_DF 的整段语义。笔必须整表重扫：最后一笔 is_sure 允许收回
+（OWN_CHAN_ZS_001 上 60 天出现 7 次）。笔中枢用 cal_bi_zs_list_pure。
