Show progress indicator while posting content

[gpunto]

Goal

At the moment, when posting a comment in the demo app we just close the "create content" bottom sheet and post it. However, the operation can take long, especially when uploading attachments without any feedback until done. So we should show a loading indicator instead.

Implementation

Move the visibility state of the "create content" sheet to the VM and, while posting, we now disable input and show a loading indicator.

Testing

Try posting something in the demo app and verify that the loading indicator is shown instead of the submit button.

Pull Request Overview

This PR implements a progress indicator for content posting operations in the demo app. Instead of immediately closing the create content bottom sheet when posting, the UI now shows a loading state with disabled input fields and a progress indicator while the posting operation is in progress.

Key changes:

• Moved create content bottom sheet visibility management to ViewModels with state flow tracking
• Added loading states that disable input fields and show progress indicators during posting
• Updated both feed posts and comments to use the new state-based approach

• The onCreatePoll method doesn't implement the same loading state management as onCreatePost. It should set _createContentState to Posting at the start and update it based on the result to provide consistent UX feedback.
