/**
 * Functional tests: per-path redirect rules.
 *
 * Creates a proxy host with structured redirect rules and verifies that
 * Caddy issues the correct redirect responses for matched paths while
 * still proxying unmatched paths to the upstream.
 *
 * The redirects_json hidden field is injected directly (same pattern used
 * for other non-labeled form controls like ssl_forced_present) so the test
 * doesn't have to click through the MUI Select for each status code.
 *
 * Domain: func-redirects.test
