The Security component renders the CrowdSec card title using the nested
translation key 'security.crowdsec.title', but the test mock only had the
flat key 'security.crowdsec'. The mock fallback returns the key string
itself when a lookup misses, causing getByText('CrowdSec') to find nothing.
Added 'security.crowdsec.title' to the securityTranslations map so the
mock resolves to the expected 'CrowdSec' string, matching the component's
actual t() call and allowing the title assertion to pass.
