feat(wishlist): implement complete wishlist API with JWT authentication

- Add Wishlist model with user reference and product IDs
- Implement wishlist controller with CRUD operations
- Add JWT authentication middleware
- Create wishlist routes with proper validation
- Add test token generation endpoint for development
- Prevent duplicate products in wishlist
- Handle edge cases (empty wishlist, invalid IDs)
- Integrate wishlist routes into main app
- Add .DS_Store to .gitignore

Endpoints:
- GET /api/wishlist - Get user's wishlist
- POST /api/wishlist - Add product to wishlist
- DELETE /api/wishlist/:productId - Remove product
- DELETE /api/wishlist - Clear entire wishlist
- GET /api/test/token - Generate test JWT token
