Bug fix
## What is the current behavior?
When a user deletes a project, the `useProjectDetailQuery` in
`RouteValidationWrapper` returns an error (HTTP 404) because the project
no longer exists. This triggers the `isErrorProject` effect, which shows
a "You do not have access to this project" toast and redirects to the
home page — even though the user intentionally deleted the project.
## What is the new behavior?
The error's HTTP status code is checked before showing the toast. A 404
response (project not found / deleted) silently redirects without
showing the misleading access-denied toast. The toast is still shown for
other error codes (e.g. 403 Forbidden), where the "no access" message is
accurate.
