+Fix taxonomy term edit dialog overflow with many locales (#1269)
+
+Adds `max-h-[85vh] flex flex-col` to the `TermFormDialog` and makes its body
+scrollable with `flex-1 overflow-y-auto`, keeping the header and footer pinned.
+This prevents the Cancel/Update buttons from falling off-screen when the
+Translations panel lists a large number of locales.
