📄 Description

Summary

Fixes OpenAPI array parameter conversion for OpenAI function calling by ensuring the 'items' property is
included in generated function schemas.

Problem

OpenAPI specs with array query parameters were generating invalid OpenAI function schemas
Missing 'items' property caused OpenAI to return 400 Bad Request: 'array schema missing items'
Issue affected tool servers using array parameters like tags filtering

Solution

Modified convert_openapi_to_tool_payload() in backend/open_webui/utils/tools.py
Added logic to copy 'items' property for array-type parameters
Ensures generated schemas are valid for OpenAI function calling

Test Plan

Tested with exact example from issue #14115
Verified generated schema now includes required 'items' property
Syntax validation passed

Fixes #14115
