fix: canvas copy/paste, note persistence, node blur

[vincentgrobler]

Description

1. Copy/paste: rewrote paste logic — removed broken nested setNodes/setEdges pattern, now uses direct state updates
2. Sticky notes: persist in config._canvas_notes field, restored when rebuilding graph from config (survives save, reload, nav)
3. Node blur: reduced backdrop-filter from 12px to 4px, raised background opacity, added will-change:transform for crisp text
