Реалистичная плата ESP32 с распиновкой + произвольные входные сигналы

Абстрактные кружки заменены на схему ESP32 DevKit с подписанными
GPIO-пинами и проводами к каждому периферийному устройству — видно,
что куда подключено. Датчик больше не ограничен фиксированными
температурой/влажностью: можно добавить любой именованный сигнал
(аналоговый слайдер или дискретный тумблер вкл/выкл) — бэкенд уже
принимал произвольный sensor_type, не хватало только формы.

Главный фикс: значения теперь публикуются в MQTT автоматически
(debounce ~350мс после слайдера, мгновенно для тумблера), а не только
по кнопке — раньше несохранённые локальные правки терялись при любом
переподключении SSE (сервер присылает эталон при каждом новом
сабскрайбе), из-за чего казалось, что слайдеры ни на что не влияют.
Плата и подписи обновляются локально сразу при вводе, без ожидания
ответа сервера.
