Research direction

Start by reviewing the linked Arduino libraries and the RV-3028-C7 datasheet to identify the chip's supported capabilities. Then locate the project's existing RTC component conventions and define done as working ESPHome support for this RTC, including the requested low-power reset use case if the project supports it.
