Description of the changes in your PR

• Wrapped the network call CommentsInfo.getMoreItems inside a try-catch block in CommentRepliesSource.kt.
• When an extraction or network exception (like UnknownHostException when offline) occurs during pagination, it now correctly returns a LoadResult.Error(e) instead of crashing the app.
• This allows Jetpack Compose's Paging 3 to catch the state and display the UI error panel (implemented in CommentSection: Add an error panel #11716) instead of triggering a fatal ACRA crash.

Before/After Screenshots/Screen Record

• Before: The app immediately crashed when trying to load more comment replies without an internet connection.
• After: The app catches the exception and displays the standard comment error UI panel with a retry button.

Fixes the following issue(s)

• Fixes CommentRepliesSource: App Crash after being offline #11717
