fix(adminui): tag-path completion replaces the whole dotted path, not just the last segment

Monaco's word definition splits on '.', so accepting a full tag path while a
partial path was typed (e.g. "X.Protected") duplicated the prefix
(-> "X.X.ProtectedValue"). Tag-path items now replace the whole literal
content from the opening quote to the caret.
