What two significant events happened in Shirdi on December 10th, as mentioned in the context of the Dixit Wada?

According to chapter 4, December 10th was a day of great importance marked by two major events. Firstly, it was the day that Kakasaheb Dixit, following Sai Baba's orders, laid the foundation for the stone Wada, a project that would provide significant accommodation for pilgrims. Secondly, the text highlights another great event of this day: the 'Shej-Aarti,' or night prayer, held in the Chavadi, also began from this very day with great devotion. This confluence of events made December 10th a particularly blessed and memorable day in the history of Shirdi.
