fix(ui): keep a typed layer or style name when the field loses focus

Renaming a layer or a style was only applied on Enter; clicking anywhere
else dropped the typed name. A click that moves focus off a field whose
text changed now commits it. New and Copy in the style managers open the
generated name for renaming, so a new style can be named right away.
