Expose Delegated Voting Functionality via Chain Extension

[deep-ink-ventures]

Objective

This ticket has a dependency to #118

To expose the newly introduced delegated voting functionality in pallet_dao_token via our chain extension. This will make the delegated voting feature accessible and usable through our chain extension API.

Affected Components

• Chain extension backend in chain-extensions/pallet-dao-assets
• contracts/extensions/dao-assets-extension
• Default implementation of contracts/extensions/dao-assets-contract

Requirements

1. Update Chain Extension Backend: Modify chain-extensions/pallet-dao-assets to include hooks or calls that interact with the delegated voting feature in pallet_dao_token.
2. Update Extension Contract: Modify contracts/extensions/dao-assets-extension to include the delegated voting functionality.
3. Update Default Contract: Make sure that contracts/extensions/dao-assets-contract exposes the new functionality.

Note

The implementation should be in line with the existing architecture and coding standards.
