eip-712-ballots

[efstajas]

This pull request introduces a wallet-based signature flow for RPGF ballot submission, ensuring that ballots are cryptographically signed by the user's connected wallet before being submitted. The changes update both the user interface and backend logic to require and handle wallet signatures, and provide more explicit feedback to users about wallet confirmation steps.

Key changes include:

Wallet Signature Integration

• Added a new signBallot utility (sign-ballot.ts) that generates a deterministic hash of the ballot, creates EIP-712 typed data, and prompts the user's wallet to sign the ballot before submission. The resulting signature and chainId are now included in all ballot submission payloads. [1] [2] [3] [4] [5]
• Updated the SubmitBallotDto type to include signature and chainId fields, and refactored ballot submission functions (castBallot, castBallotAsCsv, castBallotAsXlsx) to require and transmit these fields. [1] [2]

User Interface Updates

• Replaced the "submit" button icon and confirmation messages in the ballot upload and confirmation steps to use a wallet icon and more clearly instruct users to confirm the action in their wallet. [1] [2] [3] [4] [5] [6]
• Added an AnnotationBox to the confirmation step, informing users that a wallet signature request will be triggered and reminding them to review their ballot before confirming.

Backend API and Ballot Parsing Refactor

• Refactored spreadsheet ballot parsing and submission logic to first parse the spreadsheet into a ballot, then sign and submit it with the wallet signature, ensuring all ballot submission paths are covered by the new signature requirement.

These changes collectively enforce ballot authenticity via wallet signatures, improve user communication about wallet interactions, and streamline the ballot submission process.
