 * Auth model (see apps/edr-freight-api + freight web apps):
 *  - POST {api}/api/auth/login  { email, password }
 *    → flattened body { success, token, refreshToken } (response interceptor
 *      flattens /api/auth responses — no .data nesting).
 *  - Both web apps read cookies `auth-token` / `refresh-token` and attach
 *    `Authorization: Bearer <token>`.
 *  - Cookies are port-agnostic on localhost, so portal and backoffice share
 *    one cookie jar. cy.session snapshots/restores cookies per session id,
 *    which keeps staff and customer sessions from clobbering each other —
 *    but inside a single test, switching apps requires re-invoking the
 *    matching login command first (see flows specs).
