Incorrect TYPEHASH in rankCandidatesBySig

The TYPEHASH constant is incorrectly defined as:

bytes32 public constant TYPEHASH = keccak256("rankCandidates(uint256[])");

However, the orderedCandidates parameter is an array of address, not uint256. This mismatch leads to incorrect hash calculations, causing signature verifications to fail or allowing malicious actors to forge signatures.

Recommendation:

Update the TYPEHASH to match the correct data type:

bytes32 public constant TYPEHASH = keccak256("rankCandidates(address[])");

Ensure that all hashing and signature recovery processes use the correct data types to maintain the integrity of the signature verification.
