/**
 * Route coverage for #5918 proxy management endpoints:
 *   POST /api/settings/proxies/batch-delete
 *   POST /api/settings/proxies/auto-test
 *
 * DB-backed and network-free: batch-delete is exercised end-to-end against a
 * temp SQLite DB; auto-test is exercised only on its no-proxy early-return path
 * (which returns before any outbound probe), so no real network is touched.
