feat(washer): add label translations for detergent/softener dosing selects

Assumes the LevelCtrl code scheme is None/Low/Medium/High (00-03) on both
dispensers -- code 00 has no on-screen equivalent in the app's 3-choice
Faible/Moyen/Élevé picker, assumed to be what "Activation" off collapses
to -- and Level2Ctrl is Soft/Medium/Hard for detergent water hardness,
1x/2x/3x for softener concentration. detergent_quantity and
softener_quantity share one translation_key (same vocabulary), same
pattern as fridge.py's shared 'brightness_level' key.

Not cross-device verified: only one dump + screenshot set (issue #9) to go
on, and the softener concentration reading doesn't cleanly match its
screenshot (assumed to be a setting changed between dump and screenshots,
not a different code scheme -- see the comment in washer.py).
