[dev-overlay] fix: call stack silently fails to open editor with 204 (#75785) ### Why? When fails to find the file to open in the editor, the middleware returned `No Content` with 204 status. This caused to silently fail the open editor behavior. ### How? - Added 404 not found state for when the target file does not exist. Closes NDX-792 --------- Co-authored-by: Jiachi Liu <inbox@huozhi.im>
