CLI: Add Auth login command

[sejas]

Related issues

• Fixes STU-777

Proposed Changes

• Add Auth commands:
  • studio auth login
  • studio auth logout
  • studio auth status
• Currently it receives and saves the token through Studio App. I'm thinking to receive the token in the terminal.

Testing Instructions

• Run npm run cli:build
• Enable the studio sites cli beta feature by adding this JSON node in ~/Library/Application Support/Studio/appdata-v1.json:

  "betaFeatures": {
    "studioSitesCli": true
  }

• Run ENABLE_CLI_V2=true node dist/cli/main.js auth login

• Click on approve in your browser

• Observe you are logged in

• Run node dist/cli/main.js auth login again

• Observe the browser doesn't open again because you are already logged in.

• Run ENABLE_CLI_V2=true node dist/cli/main.js auth status

• Observe that your data is displayed in the CLI

• Run ENABLE_CLI_V2=true node dist/cli/main.js auth logout

• Observe you are logged out

Pre-merge Checklist

• Have you checked for TypeScript, React or other console errors?

I would rather not require the Studio App. Did you check the authentication command in my prototype, I have a solution for this.

Thanks for pointing that out. I'll take a look at your branch to bring the logic over here.
I initially took this approach to begin drafting the PR.

To fix this problem, we should robustly escape both double quotes (") and backslashes (\) in cliCommand before embedding it in the AppleScript script. This is needed because a backslash followed by a quote or other special sequence would defeat the quote escaping logic if not itself escaped. The best way to achieve this is to first escape all backslashes (replace \ with \\), and then escape all double quotes (replace " with \"), both globally. This can be accomplished with two chained .replace() calls using global regular expressions. It would be clearer and more error-proof to factor this into a helper function, e.g. escapeForAppleScript, but since only a single change can be made in the code block shown, we will directly perform the two-step replacement on line 307. No new imports are needed, and all changes will be confined to the assignment to escapedCliCommand.
