Loading ring should present on all feeds

[QuAzI]

1. Environment

• Device: [Samsung Note10+]
• OS: [Android 12]
• APP: 0.13.0

2. Describe the bug

While loading ring present on the main page, all other pages (Unread, Feeds) look empty. Loading ring should present on all pages where the user waiting for content to understand when you wait loading and when no content present at all

I found that it's some other problem, with loading articles at all even if no syncing in progress

Moreover... is there any way to SYNC articles from Miniflux? Not just add. Currently, I have only ~600 articles in Miniflux feed
