fix(bal): ensure sorted writes in Alloy type conversions

[doocho]

Summary

From/TryFrom implementations for Alloy EIP-7928 types now use Self::new()
to ensure writes are sorted by block_access_index.

Problem

BalWrites::get() relies on sorted data for correct binary/linear search.
However, Alloy types (Vec<BalanceChange>, etc.) do not guarantee ordering.
Using direct struct initialization (Self { writes: ... }) bypassed sorting,
potentially causing incorrect lookups.

Solution

Replace Self { writes: ... } with Self::new(...) which sorts the data.

Changes

• alloy.rs: 4 conversions updated (BalanceChange, NonceChange, StorageChange, CodeChange)
