P1-2: alloy migration — primitive & RPC-type fixes

[trial123Zel]

Roadmap task

P1-2

Problem

Roughly 40 dataset files use only stable alloy primitive/RPC types (Address, U256, B256, RPC type names). They need the mechanical fixes the alloy 0.6 -> 1.x bump requires.

Affected files

Most files under crates/freeze/src/datasets/ that import only alloy::primitives / RPC type names.

Acceptance criteria

• The affected dataset files compile against alloy 1.x.

Validation method

cargo build of cryo_freeze on the integration branch.

Completed in Phase 1 PR #63 (merged as 72d5f62). Auto-close missed this issue — GitHub's Closes #a, #b syntax only closes the first number, so closing manually.
