Fix benchmark genesis address to match block production address

[dubbelosix]

Summary

This PR addresses an issue with our benchmarking script that used a sequencer address without first registering it with the rollup. This caused all blocks to have their transactions skipped, leading to misleadingly high throughput measurements.

Changes

1. Register correct address: Now the RNG block generator used in benchmarking produces blocks that match the sequencer address registered during genesis. This ensures the benchmark properly processes the blocks.
2. Benchmark Output: A new row has been added to the benchmark output that shows the number of successfully processed transactions. This serves as an additional layer of verification for the user

Root Cause

• The benchmark script and the main code were using different types (and addresses) for sequencer addresses in genesis.
• Type checking was not in place, allowing the discrepancy to go unnoticed.
• Benchmark script was using CelestiaAddress in the genesis and rng_xfers.rs was using a default MockAddress [99u8;32] in the headers for the blocks it produced

Test Plan

1. Run the benchmark script to ensure that it no longer rejects all blocks.
2. Verify that the throughput measurement is now accurate/reasonable.
3. Confirm that the new row in the benchmark output shows the correct number of successfully processed transactions.
