Feature add n8 n (#1468)

* feat(n8n): 添加n8n工作流API支持

添加n8n工作流API作为新的运行器类型，支持通过webhook调用n8n工作流，并提供多种认证方式（Basic、JWT、Header）。新增N8nAuthFormComponent用于处理n8n认证表单联动，并更新相关配置文件和测试用例。

* chore: remove pip mirror url

* perf: simplify ret def of pipeline metadata

* feat(n8n): raise exc instead of ret as normal msg

* perf: add var `user_message_text`

* chore(n8n): migration and default config

* chore: required database version
