fix(ci): resolve PostgreSQL extension build on macOS, drop Windows

macOS: guard Security.h include behind !CLOUDSYNC_POSTGRESQL_BUILD to
avoid type conflicts (Size, uint64) with PostgreSQL headers, use
getentropy instead. Windows: dropped from postgres-build matrix — MSYS2
PostgreSQL headers expect Unix includes incompatible with MinGW.
