Use Ownable2StepUpgradeable instead of OwnableUpgradeable

Both GenesisLicense and GenesisLicenseStaking contracts inherit from OpenZeppelin's OwnableUpgradeable:

contract GenesisLicense is
    GenesisLicenseStorages,
    EIP712Upgradeable,
    OwnableUpgradeable,
    // ...

The OwnableUpgradeable implementation allows ownership to be transferred in a single transaction, which creates risk if:

1. The owner accidentally transfers to an incorrect address.
2. The private key of the new owner is not accessible.
3. The transfer transaction is front-run.

A misdirected transferOwnership cannot be undone. The protocol loses admin control of upgrade and configuration paths.

Replace OwnableUpgradeable with Ownable2StepUpgradeable in all contracts:

import "@openzeppelin/contracts-upgradeable/access/Ownable2StepUpgradeable.sol";

contract GenesisLicense is
    GenesisLicenseStorages,
    EIP712Upgradeable,
    Ownable2StepUpgradeable,
    // ...

This implements a two-step ownership transfer process where:

1. The current owner proposes a new owner (transferOwnership).
2. The proposed owner must accept ownership (acceptOwnership).

This pattern prevents accidental transfers to wrong addresses and provides stronger security guarantees for critical protocol administration functions.
