fix(fifa17): route the client's lowercase usermassinfo to the Rust handler

The retail client sends BOTH casings. Observed twice on staging, each time inside a genuine client sequence: 16:56:56 route=squad-active 200 16:56:56 GET /ut/game/fifa17/usermassinfo -> passthrough -> 502 16:56:56 route=userMassInfo 200 classify matched the exact literal `userMassInfo`, so the lowercase request fell through to the Python upstream. Today that is a harmless 502 because the upstream is dead and the client immediately retries with the canonical casing - but on a deployment with Python ALIVE that request would be ANSWERED there, silently splitting authority away from Rust for a route Core owns. That is the real defect, not the wasted round trip. Fixed with the smallest possible alias: this one tail is matched case-insensitively, the rest of the table stays exact since no other route has ever shown a casing variant. Paths are NOT globally lowercased. Tests cover the canonical casing, lowercase, uppercase, two adjacent tails that must NOT be swept up by the alias (`usermassinfox`, `usermass`), and method semantics (PUT/POST still passthrough). With the alias reverted the test fails.
