- Add missing <QHash> include: QHash<QUuid, QVector<QPointF>> was
only forward-declared transitively under Qt5's heavier headers;
Qt6's leaner <QPainter> etc. no longer pull it in.
- Replace QPolygonF{points_} with QPolygonF(points_): under Qt6,
QPolygonF inherits QList<QPointF>'s constructors via 'using
QList<QPointF>::QList;', including the std::initializer_list<T>
one. Brace-init-list construction with a single argument first
considers only initializer-list constructors before falling
back to regular ones, which trips up overload resolution here
even though points_ is exactly a QList<QPointF> (QVector is a
plain alias for QList under Qt6). Plain parenthesised
construction sidesteps that resolution phase entirely and binds
directly to QPolygonF(const QList<QPointF>&).
