The Proxy's get handler checked `prop in target` before looking up
translations. Since the target is a function, `Function.name` is a
built-in property that shadowed translation keys like `t.common.name`,
causing the raw proxy path to render instead of the translated string.
Move translation lookup before target property checks so i18n keys
always take priority. Also remove unnecessary `|| 'Name'` fallback
in CreateNotebookDialog.
