Simon Kuehn 7f2ec21c64 feat: expose eBay aspect usage tier (RECOMMENDED vs OPTIONAL) ... EbayTaxonomyService.getCategoryAspects() now returns 'usage' alongside 'required'. eBay has three effective tiers for category 177/Notebooks: required=true + usage=RECOMMENDED → hard gate (3 aspects) required=false + usage=RECOMMENDED → search ranking signal (17 aspects) required=false + usage=OPTIONAL → truly optional (11 aspects) Integration test covers all three tiers explicitly.
