refactor: make SplitGridNode full-bleed with overlay controls

Switch to fullBleed BaseNode so the image preview fills the entire
node area. Move grid config, Settings, and Split controls into an
absolute-positioned overlay at the bottom with backdrop blur,
matching the pattern used by PromptConstructorNode and other
full-bleed nodes.
