Nginx fronting Mythic 3.x redirects /graphql → /graphql/ (HTTP 301).
The sprint 8 SSRF defense (allow_redirects=False) is correct and intentional;
the fix is the URL, not the redirect policy. Upstream reference:
mythic_utilities.get_http_transport hardcodes /graphql/ with trailing slash.
Updated _GQL_URL in all three adapter test files to match.
Added TestMythicAdapterUrlConstruction regression test to prevent silent
regression on future refactors.
