Redirect to 404 Page When Note is Not Found

[Tushar504]

Description:

Currently, when a note is not found (i.e., when the API returns a notFound response), the web application continues to display the skeleton loader for the note. This behavior doesn't inform the user that the note couldn't be found.

Steps:

• Modify the code to detect when the API returns a notFound response (i.e., status code 404).
• When this happens, redirect the user to the /error route (or an equivalent 404 page).
• Ensure that the 404 page properly displays the error message and code.
