Historical replay 2: add QuarkChain account and build genesis state

[syntrust]

Summary

This PR adds the QKC-specific state encoding needed to compute historical EVM state roots:

• Add QKC account encoding with token balances, storage root, code hash, full shard key, and optional fields.
• Add QKC token balance serialization, including inline balances and token-trie backed balances.
• Add QKC account/storage trie root builders.
• Add parsing for QKC cluster genesis config, 24-byte genesis addresses, token IDs, and per-full-shard genesis allocation.
• Add the mainnet cluster config fixture and a unit test that computes all 8 QKC genesis state roots and compares them against known mainnet roots.
