task 00e: inject phonetic.Fetcher and translation.Translator into gui.New()

Add PhoneticFetcher and Translator fields to gui.Config so callers can
inject ready-to-use instances. gui.New() uses the injected values when
non-nil and falls back to constructing from provider/key fields otherwise.
The processor composition root now builds both dependencies and sets them
on gui.Config, keeping construction logic out of gui.New().
