Add allergen data to sample dishes in data.sql

[Copilot]

Sample dishes in data.sql lacked allergen data, preventing proper testing of allergen-based dish filtering.

Changes

• Added allergen mappings for all 15 sample dishes across 5 restaurants

  • 20 INSERT statements populating dish_allergens table
  • Allergens assigned based on realistic ingredients: GLUTEN (bread, soy sauce), LACTOSE (cheese, cream), MEAT (chicken, pork, fish)

• Updated .gitignore to exclude Maven target/ directory

Example Data

-- Bistro by Jelonek allergens
INSERT INTO dish_allergens (dish_id, allergen) VALUES
('d2222222-aaaa-bbbb-cccc-000000000001', 'GLUTEN'),    -- Chicken Teriyaki Bowl (soy sauce)
('d2222222-aaaa-bbbb-cccc-000000000001', 'MEAT'),      -- Chicken Teriyaki Bowl (chicken)
('d2222222-aaaa-bbbb-cccc-000000000002', 'GLUTEN'),    -- Miso Soup (miso paste)
('d2222222-aaaa-bbbb-cccc-000000000003', 'MEAT');      -- Salmon Rice Bowl (fish)

Note: Fish/seafood mapped to MEAT allergen due to enum constraints (Dish.Allergens only defines NUTS, GLUTEN, MEAT, LACTOSE).

Original prompt

Make sure the sample dishes added in data.sql have allergen data, so that the dish filtering by the allergens can be seen properly.
