  PlantAI-dev(当前主机名:9017,公网/内网自适应)
- 扩展/生信/设置/主题四按钮配文字标签(图标+文字并排,宽度自适应)
- 新增 deploy/toggle_bioflow_176.sh <off|on>:一键开关 176 生信模块

+#   bash /srv/plantai/toggle_bioflow_176.sh off   # 关生信:env=false + 重启 BFF → 生信 TAB/入口消失
+#   bash /srv/plantai/toggle_bioflow_176.sh on    # 开生信:env=true  + 重启 BFF → 生信 TAB 恢复
+# 原理:BFF main.py 按 BIOFLOW_ENABLED 决定是否注册 bioflow 反代路由;
+#       不注册时 /api/bioflow/health 返回 404,前端 probe 落 offline,生信 TAB 自动隐藏。
