/**
 * Authorization — per-entity access checks for the current user/reseller.
 *
 * Reads the current identity from the $rUserInfo / $rPermissions / $db globals,
 * so each test seeds those and tearDown clears them. The 'user' and 'line'
 * checks scope by the report tree via a real (SQLite) query; the 'adv' check is
 * pure permission logic; and everything short-circuits to false when the
 * identity globals are missing.
