fix: resolve aspect-fit failing after manual resize by aligning with React Flow dimension priority

React Flow prioritizes node.width over node.style.width for rendering.
NodeResizer writes to node.width but the aspect-fit handler was reading
from node.style and only writing back to node.style — so resized
dimensions were silently overridden. Extract getNodeDimension() and
applyNodeDimensions() helpers to read/write both sources consistently.
Also removes an unused Zustand store subscription that caused unnecessary
re-renders.
