Configure Sepolia Frontend for Transaction Price Display

[Tanya-ruby]

Objective:
Ensure Correct Fetching and Display of Transaction Prices:
The Sepolia frontend must accurately fetch and display the current transaction prices for Stablecoin and Reservecoin transactions. This involves correctly interpreting and applying the rcDecimals, scDecimals, and BC_decimals parameters to calculate and present transaction costs accurately.

Current Behavior:
Incorrect Estimation of Transaction Costs:
Users attempting to obtain 10,000 Stablecoins are currently being estimated to require 0 ETH for the transaction. This discrepancy indicates a fundamental issue with how the rcDecimals, scDecimals, and BC_decimals parameters are configured or utilized within the frontend's calculation logic.
