feat: support multiple valueTypes for text input variables (#6801)

* feat: 文本输入框变量支持多 valueType

* fix: 文本输入框变量非 string valueType 的渲染映射

- formRender/utils.ts: variableInputTypeToInputType 在 text input 场景下
  按 valueType 派生，非 string 走 JSONEditor/textarea，让 Chat 表单与
  调试面板能正确渲染 object/array/any 变量
- packages/global/core/workflow/utils.ts: appData2FlowNodeIO 的
  renderTypeMap 对 text input + 非 string 使用 [JSONEditor, reference]，
  保证父工作流节点输入同步跟进
- 补 appData2FlowNodeIO 的 text input valueType 分支测试

* feat(workflow): 全局变量联动清理节点引用及变量更新节点必填校验

* fix(workflow): 文本输入变量 legacy 兼容与引用存活校验

* refactor(workflow): 抽出文本输入变量 valueType 兜底 helper

* feat: adapt test for all node type

* revert(workflow): 移除全局变量引用联动清理

* feat: remove any in text input

* doc
