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

- Add internal/adapters/ai/types.go with neutral shared types
(Recipe, DayPlan, RecognizedItem, IngredientClassification, etc.)
- Remove types from internal/adapters/openai/ — adapter now uses ai.*
- Define Recognizer interface in recognition package
- Define MenuGenerator interface in menu package
- Define RecipeGenerator interface in recommendation package
- Handler structs now hold interfaces, not *openai.Client
- Add wire.Bind entries for the three new interface bindings
To swap OpenAI for another provider: implement the three interfaces
using ai.* types and change the wire.Bind lines in cmd/server/wire.go.
