explorer/site: enhance explorer UI to display total network and trx gas consumption

This comment introduces UI updates to display total network gas consumption statistics across all transactions, as well as individual transaction gas consumption. These updates enhance the understanding of gas consumption by providing insights that can help users set appropriate gas limits, identify peak usage and anomalies, manage costs, and optimize blockchain performance.

Update Summary:

- Explorer Home Page: The `index.html` file has been updated to include a new section that displays total network gas consumption statistics, covering total gas, WASM gas, ZK circuits gas, signatures gas, and deployments, along with their average, minimum, and maximum values.

- Transaction Details Page: The `transaction.html` file has been updated to include gas consumption metrics and timestamp for individual transactions.

- Index Route: The index route in `app.py` has been modified to retrieve metrics statistics.

- RPC Module: The `rpc.py` file has been updated by introducing a new function to retrieve metrics statistics from the blockchain-explorer daemon.
