feat (gui): interactive configuration guide

[reycn]

Secenario

It is still difficult for the average person to use the application.

Feature

As a solution, this feature request proposes the following:

• Add an interactive tutorial for users to set up
  • If the user selects Google as the service, enter the main interface
  • If the user selects any other services with configuration required, enter tutorial and provide additional external links to the service chosen
• The tutorial will begin with a check and a demonstration
• The tutorial will appear only when:
  • The user starts the interactive mode for the first time
  • The user proactively clicks on the tutorial button
• *The interactive mode with tutorial checks set as the default method if without any additional arguments, i.e., pdf2zh in the command line.
