fix(catalog): decode and strip stray markup from product descriptions

P0-5: some catalog listings (live backend data, proxied third-party
marketplace via novo.market) carry HTML-entity-encoded markup in
their description field, e.g. '<attention>...</attention>'
and '"AppStops"' — rendered verbatim as visible text on
search-result cards and the PDP description tab.

Added a pure cleanDescription() util (item.utils.ts) that decodes
the common HTML entities and strips any resulting tag-like markup,
then wired it into ProductCardComponent (covers Home/Catalog/Search/
Wishlist/Compare/PDP-similar) and ProductDescriptionComponent (PDP
description tab). Output stays a plain string rendered via text
interpolation (never innerHTML), so this only cleans up display —
it introduces no HTML-rendering/XSS surface.
