P0-4: the Catalog/Search category facet showed placeholder labels
like 'Категория 2008', 'Категория 22612' for every option — traced
to search.facade.ts buildFilterGroups() synthesizing 'Category {id}'
for every distinct product.categoryID with no attempt to resolve a
real name.
Investigated further: the mismatch isn't a missing-lookup bug, it's
a real data gap. Product categoryID values in the mock catalog
fixture don't correspond to any id in CategoryFacade's category
tree (a much smaller, separately-curated mock dataset) — there is
no real category name to show for these ids today.
Wired CategoryFacade into SearchFacade and resolve each option's
real title when the id does match; when it doesn't (the common case
with current mock data), the option is dropped rather than showing
a fabricated technical-looking label. The category filter group
simply doesn't render when nothing resolves, which is honest given
the data, instead of looking like broken/unseeded content in front
of a client.
