chore: update contracts

[leovct]

Description

• Generate a new version of the ERC20 bytecode. It was always reverting during the deployment.
• The contracts/ folder is now a foundry project which makes it easier to handle dependencies.
• ERC20.sol and ERC721.sol have been rewritten to use openzeppelin standards.
• Add new CI job to make sure contracts can be built using forge.

Jira / Linear Tickets

• DVT-1075

Testing

• Deploy ERC20 smart contract from bytecode.
