LWOBaseVendorComponent is the base of the client's vendor, donation vendor and achievement vendor; DLU's vendor logic becomes BaseVendorComponent with VendorComponent, DonationVendorComponent and AchievementVendorComponent all built on it (the last two derived from VendorComponent before). Nothing sent changes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
