// Security tab — read-only smoke test.
//
// One single login, then walk every Security panel + sub-tab and
// assert each renders its hero element. NO destructive flows
// (no bans added, no firewall toggles, no signature pulls) — those
// have dedicated specs.
//
// Single-test design (vs one test per tab) on purpose:
//   - Kratos rate-limits login at 5/min; one test per tab tripped it.
//   - Smoke = end-to-end walkthrough. Failing fast on the first broken
//     panel is exactly what we want — later panels still need a
//     working shell to even render.
//
// Required env:
//   E2E_BASE_URL  https://jabali-panel.local
//   E2E_USERNAME  admin@example.com
//   E2E_PASSWORD  ...
