fix: add missing node and handle types to quickstart validation

VALID_NODE_TYPES was missing audioInput, promptConstructor, outputGallery,
imageCompare, videoStitch, easeCurve, videoTrim, videoFrameGrab, and glbViewer —
all of which are defined in NodeType and have entries in DEFAULT_DIMENSIONS and
createDefaultNodeData. VALID_HANDLE_TYPES was missing video, easeCurve, and 3d
handle types used by EaseCurveNode, GenerateVideoNode, Generate3DNode, GLBViewerNode,
VideoStitchNode, VideoTrimNode, and VideoFrameGrabNode.
