test: assert Azure endpoint hostname instead of substring match

CodeQL flagged the `"test.openai.azure.com" in llm.endpoint` substring
check as incomplete URL sanitization — the substring could match in
an arbitrary position. Parse the URL and assert against
`urlparse(...).hostname` instead, which is the precise check we want.
