Auction data for Validators in a single RPC response

[devendran-m]

Problem Statement:
Currently, querying auction-related data requires making separate calls for each bid, which is highly inefficient when managing a large number of bids. This inefficiency complicates workflows for developers and hinders network transparency. Additionally, without a streamlined method or a network explorer like CSPR.live, it becomes challenging to self-discover this critical information, impeding the development of tools and features like liquid staking.

User Story based on the requirement: (as outlined by MAKE Services team to Jakub in a chat);
As a: Blockchain Developer
I want to: retrieve detailed auction-related information for all bids in a single RPC response
So that I can: improve the efficiency of bid queries and enhance network transparency for developers and stakeholders.

Estimated benefits:

• This improvement aligns with ongoing efforts to implement liquid staking and other staking-related features.
• It supports developers in building robust solutions that leverage Casper Network's validator data.
