ListaDAO: clisBNB officially renamed slisBNBx

On July 3, ListaDAO officials posted on social media that in order to improve product clarity and user recognition, clisBNB has been renamed slisBNBx as one of the sub-products of Lista's core liquidity pledge token slisBNB. Existing users do not need to do anything, the system will automatically convert to slisBNBx, and the functions will remain unchanged.
