Implement `eth_getProof` for "latest" Tag in Erigon 3

[Giulio2002]

Description:
Add support for the eth_getProof JSON-RPC method in Erigon 3 to handle the "latest" tag, enabling retrieval of account and storage proofs for the most recent block.

Tasks:

1. Update the eth_getProof method to support the "latest" tag.
2. Ensure accurate proof generation for accounts and storage.

Acceptance Criteria:

• eth_getProof works with the "latest" tag and returns correct data.
