[Improve] Execute root actions from HelperTool

[NghiaTranUIT]

🐶 Brief

Currently, there are several action that need proper authentication from users, such as:

• Auto Install Key to Keychain
• Delete keychain
• Generate certificate on non-admin user
  Each of action need to prompt the User authentication, which is bad UIUX

I would suggest to delegate this work to Helper Tool if it's already installed at the first launch. Thus, we don't need to prompt anymore.

👑 Criteria

• Delegate some work to Helper Tool
• Keep the old code for roll-back action
