Add tokens to RoboFi Wallet

Each DABot can circulate bot tokens of itself, which means the more DABots, the more tokens exist in the system. RoboFi Wallet helps users to store VICS, sTokens (sUSDT, sBUSD,...), bot G-tokens and C-tokens, as well as popular crypto assets (USDT, BUSD, ETH, BNB…) in users' own wallets.
