feat: Initialize nodes on canvas mount and improve logging

[CocoRoF]

This pull request introduces functionality to initialize and refresh nodes when the Canvas component is mounted. It integrates a new hook and ensures proper logging for debugging purposes. Below are the key changes:

Integration of useNodes Hook:

• Added an import for the useNodes hook in Canvas.tsx to enable node-related operations.
• Utilized the exportAndRefreshNodes function from the useNodes hook within the Canvas component to manage node initialization.

Node Initialization on Mount:

• Introduced a useEffect hook to call exportAndRefreshNodes when the Canvas component is mounted. This ensures nodes are initialized and refreshed at the start. Additionally, added logging for successful execution and error handling to aid debugging.
