fix(icons): replace hand-rolled inline SVGs with Lucide (cart, selectors, carousel)

Cart: trash/X/plus/minus/lock icons replaced with app-icon. Removed
the standalone EmptyCartIconComponent entirely - it was a duplicate
80px shopping-cart glyph with no unique illustration, only ever used
in one place; now app-icon name="cart" inline.

Language/region selectors: dropdown chevrons (duplicated 3x with
identical path data across two components) unified on
chevronDown; region pin, locate (crosshair), and globe icons replaced.
New mapPin/locate icons added to the registry.

Items carousel: rating star and add-to-cart icons replaced.
