KiCad 10.0.4 added two trailing optional params (std::optional<VECTOR2I>
aMousePos, wxString* aActiveUrl) to the out-of-line FONT::Draw declaration
in font/font.h. The hand-written stub in the GAL WebGL test app still
declared the old 6-arg form, so it matched no declaration and failed the
CI "Build GAL WebGL test app" step. Update the stub signature to match.
