Improve the component VotingPower

[arielmergen]

Feature or change description

Now the component is taking the Hemi token symbol and simply appending the text, resulting in veHemi. Instead, it needs to fetch the symbol directly from the contract.

Problem or use case addressed

Proposed implementation

Once you obtain the token, do the following:

• Validate the loading state; while it’s loading, display a skeleton (the components already exist, just implement them).
• If there’s an error, fall back to ve${token.symbol}.
• Recalculate the votingPower.
• Display the token.
