Add confirmed washer/dryer cycle code labels (issue #80)

Five raw course codes were rendering unlabeled because no translation
entry existed for them, confirmed by the reporter selecting each cycle
on the physical appliance and reading back the raw code from the
entity's state:

- washer_cycle_table_02: '52' Eco Cold, '54' Towels, '60' Self Clean+
  (a WF50A8600AV/US). '54' shares a display name with the existing '24'
  Towels -- a different code on the same table legitimately landing on
  the same label, matching the existing '21'/'65' Colors and
  '27'/'5E' Rinse+Spin pairs, not a duplicate-in-error.
- dryer_cycle_table_03: '01' Normal, '06' Time dry (a DVE50A8600V/A3,
  the same model added in the previous commit's detection fix).

No code changes -- select.py already derives which raw values it
normalizes from the shipped catalog, so labelling a code is purely a
translations/en.json (mirrored to nl.json) addition.
