feat: canvas history (undo/redo), copy/paste nodes, node search, shortcuts modal

- Undo/Redo (Ctrl+Z / Ctrl+Y): 50-entry snapshot stack in canvasStore; snapshot before all mutations and on node drag stop - Copy/Paste (Ctrl+C / Ctrl+V): copy selected nodes to clipboard, paste with +50px offset and new IDs - Node search (Ctrl+K): spotlight overlay — fuzzy search by label/IP/hostname, jumps + focuses matched node - Shortcuts modal (?): lists all keyboard shortcuts, accessible via ? key or toolbar ? button - Toolbar: undo/redo buttons (disabled when stack empty), ? help button
