Offline Mode: Sync Publishing

[kean]

Part of https://github.com/wordpress-mobile/WordPress-iOS/issues/22579

To test:

[!IMPORTANT]
Make sure to enable the .offlineMode feature flag.

• Tap "+" to create a new post
• Add content and tap "Publish"
• Verify that the pre-publishing sheet is shown
• Tap "Publish"
• Verify that that sheet is disabled and can't be dismissed during publishing
• Verify that if request fails, a snackbar is shown (note: it should not have a "Retry" button)
• Verify that if request succeed, the editor is dismissed

This is the only scenario that is now officially supported. We'll need more tests, including automated test in the future PRs.
