"""FUT roster-update HTTPS server for FIFA 17 (OpenFUT).

The FUT loading flow (checkFUTRostersFlow / state CheckFUTRosterUpdateXML) downloads
a roster-update XML from ROSTERUPDATE_URL (which blaze_responder_v3b.py now serves as
https://127.0.0.1:8081/fifa17/fut/rosterupdate.xml). On download SUCCESS the flow
raises `advance` -> CheckFUTSquadBinFile -> (no squad) -> EnterFUT -> CardsDLL loads.
On FAIL it raises `back` -> abort. So this must return something FIFA ACCEPTS.

We don't have (or need) EA's real roster: the base player DB is baked into CardsDLL;
the roster-update is an optional delta. Start by serving a minimal "no update" body,
LOG every request (path/headers) so we learn exactly what FIFA fetches, and iterate.

HTTPS because EA's value is https and the DirtySDK download mgr may reject http; FIFA's
ProtoSSL cert-verify is patched (autopatch), so our self-signed cert is accepted.
