washer_cycle_fallback no longer wraps an unrecognized code in an
'Unknown (0xNN)' label -- that baked untranslatable English into a
component built to be fully translatable. It now only ever surfaces a
device-provided personal-course name; an unrecognized standard code
displays as its raw value, same as before PR #251.
Also translates nl.json's '69'/'88' washer labels left in English (same
review), and makes de.json's own 'smart' states consistent with the
'Intelligente Lüftung' translation already used for smartventilation.
