refactor: changes to use wallet-lib v1.1.0

[pedroferreira1]

Acceptance Criteria

• Bump lib version to the latest (v1.1.0)
  • The previous lib version was really old and many lib dependencies have changed. Because of that, the package-lock.json update was not easy, then I decided to also fix the versions of all dependencies in the package.json with the ones from the package-lock.json and run a full update in the package-lock.json file.
• Update code for the new lib methods

Security Checklist

• Make sure you do not include new dependencies in the project unless strictly necessary and do not include dev-dependencies as production ones. More dependencies increase the possibility of one of them being hijacked and affecting us.
