/**
 * TDD — #6246 IP leak (part 1, fail-closed).
 *
 * When a proxy is ASSIGNED to a connection (account/provider/global scope) but is
 * dead/inactive, `resolveProxyForConnection` returns a direct result (no alive
 * proxy resolved). The chat path used to egress DIRECTLY in that case, leaking
 * the operator's real IP. The fix is a fail-closed guard: if the only reason a
 * connection resolves to direct is that its ASSIGNED proxy is dead, block instead
 * of leaking. Explicit "proxy off" toggles are a deliberate direct choice and must
 * NOT be treated as a leak.
 *
 * This test exercises the pure DB predicate `hasBlockingProxyAssignment`, which
 * encodes exactly that decision (honoring the global + connection proxy toggles).
