enable_loop_soon_any_context() sets volatile flags but does not wake the main loop from ulTaskNotifyTake() sleep. This means components using ISR-driven state changes (e.g. GPIO binary sensors) wait up to ~16ms for the select timeout before their loop runs. Add Application::wake_loop_isrsafe(nullptr) to immediately wake the main loop when called from ISR context on platforms with fast select. Also relax the wake_loop_isrsafe() guard from requiring both USE_WAKE_LOOP_THREADSAFE and USE_LWIP_FAST_SELECT to just USE_LWIP_FAST_SELECT, since the ISR wake path uses vTaskNotifyGiveFromISR directly and does not depend on the UDP socket mechanism.
