Proposed Changes

• Remove status code check in screenshot capture flow to ensure site screenshot is taken even if there's a site error. This will provide clear feedback to the user that the site isn't working. The screenshot will capture the site as-is.

Before	After

Testing Instructions

1. Check out the PR branch and build the app with npm install && npm start.
2. Create a site and make it crash in some way. For example, you can:

• open the site's wp-content/ and remove the following from it:
  • database/
  • db.php
  • mu-plugins/sqlite-database-integration

3. Restart the site.
4. The error should be captured in the site screenshot in Studio (instead of current Preview unavailable message).

Pre-merge Checklist

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

I think this is good 👍 It worked as expected for me:

I went through the code as well and I think it makes sense to remove that bit.

Love PRs that just remove code and improve the user experience.
I confirm the screenshot is captured even if the website returns an error.
