dryer: translate dryer_type, folding in #366's Dutch additions

#366 added Dutch state translations for dryer_type ('Electricity') and
progress, but predates #371's lowercase-key normalization: its progress
states were already superseded (every one it added is already in nl.json's
current 'state' table, lowercase), and its dryer_type addition used the
pre-#371 capitalized key.

dryer_type itself was never wired for translation at all -- no
device_class, no options -- so nothing in any locale's dryer_type.state
table was ever read. Give it device_class=enum, options=("electricity",)
(the only value confirmed across shipped fixtures), and the same
value_fn=lower() normalization #371 used elsewhere, then add the
'electricity' state across all seven locale catalogs, not just Dutch.
