Round-5 fix: relabel bakery_food_shop "food shop" (no false 'bakery' claim)

Both round-5 reviewers converged on the SOLE remaining MAJOR: a wine shop
("Trois Fois Vin", OSM shop=wine → bakery_food_shop) was narrated "another
bakery along the way" — a false, verifiable label. The category bundles
bakery/patisserie/wine/cheese/deli, so render it "food shop" (always true).
Sole change to pretty_category.
