Subject: [PATCH] feat: Add total voters and tokens staked from blockchain
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Fetch total staked tokens from pallet_staking.erasTotalStake()
- Count unique voters from pallet_conviction_voting.votingFor.keys()
- Display real-time data instead of hardcoded values
- Shows '-' when data is unavailable (e.g. no current era)
