/**
 * Regression for the Passport /oauth/clients* authorization bypass.
 * Passport's default client-management routes are auto-registered by
 * its service provider with only web + auth:web middleware, so any
 * session-authenticated user could POST /oauth/clients with an
 * attacker-controlled redirect URI. If a phished admin then approved
 * the resulting consent screen, the attacker exchanged the auth code
 * for a long-lived bearer token carrying the admin's full API
 * permissions.
 *
 * The fix registers overriding routes at the same URIs in
 * routes/web.php (loaded before Passport's package service provider
 * boots, so FIFO route resolution picks ours) gated with
 * authorize:superuser to match the /admin/oauth surfaces Snipe-IT
 * already treats as superuser-only.
