feat(web): add an interactive Compositor node canvas

Browse Source 
Author Compositor graphs in the web UI with React Flow and execute
them locally. The native writer materializes RGB/Exposure/Invert/Blur/
Mix/Alpha Over/Transform/Viewer/Composite nodes into a real
CompositorNodeTree, the reader returns node locations and more node
types, and save/reopen keeps nodes, links, positions and properties.
