Two tests added while triaging #244/#226 just re-asserted a translation
string against the catalog entry that had been written moments earlier
(dryer_cycle_table_03's '51'/'53'/'4e', dishwasher_cycle's '83'/'86').
Neither exercises any code path -- they pass by construction and only
break when someone later edits the label text for wording, not when the
actual code/value mapping regresses. tests/test_translations.py already
holds the invariants that matter for catalog data.
Documents the anti-pattern in the adding-device-support skill so future
translation-only fixes don't reach for this pattern again.
