Install SFML via vcpkg and simplify CI steps

Standardize CI step names and simplify vcpkg installs by replacing feature-specific targets (sfml[graphics,window,system]:x64-... ) with the plain sfml:x64-* packages for Windows, Linux and macOS. Also remove a redundant comment about DLL copying. These changes simplify the workflow and rely on the default SFML package configuration in vcpkg.
