RecognizeDish() and buildRecipePrompt() were generating text in the
user's language and storing it in base tables, violating the project
rule that base tables always hold English canonical text.
- RecognizeDish(): hardcode English for dish_name; enrichDishInBackground()
now correctly translates FROM English into all other languages
- buildRecipePrompt(): remove langName lookup, hardcode English for all
text fields; drop unused locale import
