Note

Adds ownable-controlled mint/burn to DualCaseERC20Mock and introduces IMintableToken (+ camelCase variant) interfaces.

• ERC20 Mocks
  • packages/utils/src/erc20/erc20_mocks.cairo
    • DualCaseERC20Mock:
      • Integrates OwnableComponent (storage + events) and initializes ownership in constructor.
      • Constructor now takes owner (replaces recipient) and mints initial supply to owner.
      • Implements IMintableToken and IMintableTokenCamelOnly with owner-restricted permissioned_mint/permissioned_burn and is_permitted_minter.
• Interfaces
  • packages/utils/src/interfaces/mintable_token.cairo: Adds IMintableToken and IMintableTokenCamelOnly traits.

1. how is it applicable in current context?
2. allowing any user to burn to any other user is a bit aggressive even for testing... although legit
3. might be handy to be able to create supply as well
