Unable to edit or delete my projects — API endpoints returning 404

[btar1gan]

The edit and delete functionality is broken for my projects. The frontend JavaScript still references /api/update/<nickname>/<project-slug>/ for both POST (save) and DELETE operations, but these endpoints now return 404 Not Found.

I have confirmed this by:

1. Opening the edit page manually
2. Inspecting the JS source — it still references /api/update/<user>/<slug>/
3. Sending the DELETE request manually with valid session cookie + CSRF token → 404
