Optimization :Lack of Multicall Implementation (djed-sdk)

[aniket866]

• Issue: getCoinDetails in djed-sdk/src/djed/system.js performs ~6-8 separate RPC calls (totalSupply, scPrice, R, etc.) in parallel.

• Impact: This floods the node with requests. Browser limits on concurrent connections (usually 6) will cause these to queue (waterfall), significantly slowing down the initial data load.

• Fix: Implement a "Multicall" pattern (using a Multicall contract) to aggregate these into a single RPC request.
