R7S Legends Database v3.5.97 — Preud'homme Benfica hotfix

R7S Legends Database v3.5.97 is based on v3.5.96. The correction changes only Michel Preud'homme's canonical current-team assignment from KV Mechelen to SL Benfica. His existing Benfica 1994–1999 history remains unchanged at 147 appearances and 0 goals. The package passes static validation and still requires runtime retesting.
