switch to useLcdClient after it supports static wallet

[eng4753]

currently useLcdClient() hook from wallet-kit can only be called when wallet is connected, we used to have a static wallet from the old wallet-provider library to use when user didn't connect the wallet on the app, but it's no longer available, so in order to display dummy data we need to set LCD manually

setLcd(LCDClient({
    [CHAIN_ID]: {
      lcd: LCD_ENDPOINT,
      chainID: CHAIN_ID,
      gasAdjustment: 3.5,
      gasPrices: { [CHAIN_DENOM]: 0.015 },
      prefix: CHAIN_PREFIX, // bech32 prefix, used by the LCD to understand which is the right chain to query
    },
  }))

Ideally we can just use useLcdClient()
