HTTPS_PORT — второй Netty-сервер с тем же HttpHandler и тем же сертификатом, что SMTP/IMAP (Let's Encrypt от acme, перечитывается при продлении). HSTS добавляет Spring Security. docker-compose.public.yml: 443 → 8443. HTTP 8080 остаётся для прокси внутри сети. Тесты: HttpsConfigTest, всего 74; живой запуск: /api/config по HTTPS, HSTS.
