[FIX] website_sale: fix nested category list width in product aside

__Issue:__
In the product categories sidebar (`#products_grid_before`), nested
`<li>` elements could become wider than their parent `<ul>` when the
category names were long (e.g., "Untersuchungshandschuhe"). This caused
the parent <ul> to expand in height before the child and broke the
visual layout.

__Fix:__

Force `<li>` elements inside the `#categories_recursive` list to respect
their parent width by applying `width: 100%` This keeps the sidebar
layout consistent even with long category names.
