#5127264 Jetpack: Handle disconnected site case

When either sites-rewind or sites-scan endpoint returns a response object with no_connected_jetpack code and 412 status, we know there is some issue with the Jetpack Connection. Currently, we are not handling this case, and we show users a blank screen that tells them nothing.

Changes proposed in this Pull Request

• In both the Jetpack Backup and Jetpack Scan sections, show a special page for when the Jetpack Connection is not working.

Testing instructions

Prerequisites: Jetpack Site, and WPCOM sandbox.

• Run this PR (both Calypsos).
• Select a site with a paid plan (we want a site that has both Jetpack Backup and Jetpack Scan).
• Visit the Jetpack > Backup section.
• Verify that everything looks normal and you can see your site’s latest backup.
• Visit the Jetpack > Scan section.
• Verify that everything looks and you can see the current state of Scan.
• Modify /wp-content/rest-api-plugins/endpoints/sites-rewind.php and /wpcom-sandbox/wp-content/rest-api-plugins/endpoints/sites-scan.php from your sandbox to make these endpoints return a 412. In the first file, on line number 72, you will have to remove the ! from the if condition. In the other file, do the same but on line number 290. Please reach out to me if you need help with this.
• Sandbox public-api.wordpress.com.
• Visit the Jetpack > Backup section.
• Verify that you see a new page that tells you there is a problem with the Jetpack Connection.
• Verify that the first button takes you to a page within WordPress.com, while the second takes you to our Support pages.
• Visit the Jetpack > Scan section.
• Verify that you see a new page that tells you there is a problem with the Jetpack Connection.
• Verify that the first button takes you to a page within WordPress.com, while the second takes you to our Support pages.
• Repeat this process in Jetpack Cloud.
