Subject: [PATCH] fix(workflow): handle 'number' DTO type in variable
 conversion (fixes #2645)

The backend can return 'number' as a DataType (DataTypeNumber = float64) for
plugin output parameters, but the frontend VariableTypeDTO enum in
@coze-workflow/base only defined 'float' and 'integer'. This caused
DTOTypeToViewType to throw "Unknown variable DTO Type: list:number" when adding
a plugin with nested array<number> output parameters to a workflow.

- Add `number = 'number'` to VariableTypeDTO enum in dto.ts
- Handle VariableTypeDTO.number (fall-through to float) in DTOTypeToViewType
- Add VariableTypeDTO.number entry to VariableType2JsonSchemaProps map
