fix(actions): keep NSID input focused and drop stale schema errors while typing #85

Fixed: the NSID input no longer loses focus in the record and patch-record actions, and a stale “Not found” error clears as you keep typing. Not verified in a browser: the tests didn’t reproduce the blur in happy-dom, so the focus fix follows the issue’s diagnosis. Please check it in the dev server. Remaining behavior: an incomplete NSID left untouched for over 400ms can still show “Not found” until the next keystroke.
