ac92567 fix: pass verify=False at httpx client construction for MCP SSL bypass

📄 Description

Setting client.verify = False after httpx.AsyncClient construction does not affect the underlying transport's SSL context - the SSL context is configured during init and cannot be changed afterward. This caused MCP tool connections to always verify SSL certificates even when AIOHTTP_CLIENT_SESSION_TOOL_SERVER_SSL was set to false.

Build the httpx.AsyncClient directly with verify=False in the constructor kwargs to properly disable SSL certificate verification.

Fixes #21481
