[FEAT] Create table listing liquid staking pools

[yurixander]

• Liquid staking in the Parachain will utilize the concept of "pools" rather than individual validators.
• During liquid staking, a table listing all the available pools should be shown, which would allow the user to select which pools to stake onto.
• Each table row should show the relevant pool information, such as what validators are within it, the pool owner, total value staked, APY, and any other relevant information.
• Each pool is unique regardless of its validators; for example, there can be two pools with the same validator set, and still be considered different.
• Note that the Liquifier smart contract (deployed on Ethereum Mainnet) does not support pools as of now, so the validator table should still be shown for it.
