Update the lottery NFT to ERC1155

[ChefHopper]

The lottery logic currently relies on a ERC721 token to handle NFT tickets.

Owing to technical limitations (no batch minting) in the ERC721 standard, it is essential to update the lottery logic with a new LotteryNFT built under the ERC1155 standard.

The purpose of this change is to batch mint tickets, which will result in massive gas reduction for users, and allow greater participation from users.
