/**
 * Regression coverage for GitHub #19334: /users/{id}/assets, /accessories,
 * /licenses, and /eulas emitted pagination metadata but returned every row,
 * ignoring ?limit and ?page. Each test seeds N rows for the target user and a
 * few extra rows for a bystander user (so we also catch a "return everything
 * across all users" regression), then asserts total, rows count, per_page,
 * current_page, and next/prev URL against a specific ?limit/?page query.
