* test(e2e-ui): check the MCP Tools tab against the upstream's own tools/list
DeepWiki renamed ask_question to ask_wiki_question, and the spec hardcoded the old name, so
e2e_ui_testing went red on main for something that is not a litellm regression. The spec now asks
the upstream server for its tool list with the official MCP TypeScript SDK and expects the tab to
show exactly those cards, so a vendor rename cannot turn the job red again.
* test(e2e-ui): cite the pinned DeepWiki tool name and drop the helper docstring
