LowInherited OwnableUpgradeable uses single-step ownership transferFixed

During the code review, It has been noticed that the EmailNameService, NickNameService contracts use single-step ownership transfer on the OwnableUpgradeable contract.

LowUsed locked pragma versionFixed

The pragma versions used in the contract are not locked. Considerusing the latest versions among 0.8.19 for deploying the contracts and libraries as it does not compile for any other version and can be confusing for a developer. Solidity source files indicate the versions of the compiler they can be compiled with.pragma solidity ^0.8.0; // bad: compiles between 0.8.0 and 0.8.19 pragma solidity 0.8.0; // good: compiles w 0.8.0 only but not the latest version pragma solidity 0.8.19; // best: compiles w 0.8.19
