[FEAT] Expected Rewards Display for Restaking

[monaiuu]

Description

Create a display to showcase expected rewards for users who have deposited assets into Tangle's restaking vaults. This feature aims to incentivize users to keep their assets locked by providing visibility into potential future rewards, even when immediate rewards may not be apparent for smaller deposits.

Objectives

• Aggregate deposits across various restake vaults for each user.
• Calculate and display expected rewards over different time periods (e.g., 1 month, 3 months, 1 year).
• Provide a clear UI to showcase potential rewards.
• Ensure the display is accurate and updates based on current staking conditions.
