/**
 * #6246 — "Massive issue with proxies since 3.8.44 - IP leak" (delta scope).
 *
 * The core fail-closed + scheduler regression is fixed in PR #6296. This suite
 * covers the two remaining reporter asks that #6296 does NOT touch:
 *   (#3) the "Test All" button (`/api/settings/proxies/auto-test`) must be a test,
 *        not test-and-set — it flipped a proxy to `inactive` on a failed probe,
 *        and the egress selector excludes `inactive` proxies, so "Test All"
 *        silently disabled every proxy that failed a flaky probe;
 *   (#4) a bulk enable/disable endpoint so an operator can re-activate proxies
 *        in one action.
 *
 * DB-backed and network-free: the probe targets a dead localhost proxy
 * (immediate ECONNREFUSED — no outbound traffic).
