Refactor: Per-Token Configuration and Permit-Based Minting

This pull request introduces a significant refactoring of the ArtToken and AuctionHouse contracts to support per-token configuration and a more robust permit-based minting system. The changes move away from a collection-level regulated flag to a more flexible regulationMode that can be set for each individual token.

Summary of Changes

• Per-Token Configuration: The concept of a collection-wide regulated status has been replaced with a TokenConfig struct for each token, which includes a creator address and a regulationMode enum (Unregulated or Regulated).
• Permit-Based Minting & Auction Creation: The buy function in ArtToken and the create function in AuctionHouse have been updated to use EIP-712 permits (TokenMintingPermit and AuctionCreationPermit).
• Contract Refactoring:
  • ArtToken now includes an ArtTokenConfigManager to handle the new per-token configurations.
  • The Distribution library has been replaced with a more generic SafeERC20BulkTransfer library for handling revenue distribution.
  • Structs like Auction and Order have been moved into their own libraries for better organization.
• Test Updates: All related tests have been updated to align with the new contract interfaces and functionality.

Detailed Changes by Contract

ArtToken.sol

• Removed buy function: Replaced with a new mint function that accepts a TokenMintingPermit and a signature.
• Renamed mint to mintFromAuctionHouse: This function is now specifically for the AuctionHouse to mint tokens after a successful auction.
• Introduced ArtTokenConfigManager: A new contract to manage TokenConfig for each token, with functions to get and set the creator and regulationMode.
• Removed REGULATED flag: The collection-level regulated boolean has been removed in favor of the per-token regulationMode.
• Replaced Distribution with SafeERC20BulkTransfer: The logic for distributing funds from a primary sale now uses the SafeERC20BulkTransfer library.

AuctionHouse.sol

• Updated create function: Now uses an AuctionCreationPermit to create new auctions, requiring a signature from an authorized signer.
• Updated finish function: When an auction is finished, it now calls ArtToken.mintFromAuctionHouse and passes the TokenConfig for the new token.
• AuctionHouseStorage: Now includes a mapping to store the TokenConfig for each token in an auction.

Market.sol

• Renamed ExecutionPermit to OrderExecutionPermit: For clarity and consistency.
• Renamed Order.Side enum members: ASK is now Ask and BID is now Bid.

Other Changes

• CollectionDeployer.sol: Updated to remove the regulated parameter during deployment.
• Configuration Files: The regulated field has been removed from config.dn.yaml and config.do.yaml.
• Dependencies: Updated various dependencies in package.json.
