/**
 * CrowdSec Banned IPs (Decisions) E2E Tests
 *
 * Tests the CrowdSec banned IPs functionality on the main CrowdSec config page:
 * - Viewing active bans (decisions)
 * - Adding manual IP bans
 * - Removing bans (unban)
 * - Ban details and status
 *
 * NOTE: CrowdSec "Decisions" are managed via the "Banned IPs" card on /security/crowdsec
 * There is no separate /security/crowdsec/decisions page - functionality is integrated.
 *
 * @see /projects/Charon/docs/plans/current_spec.md
