JetNews

Describe the problem

1. Redundant or outdated KDoc entry
   A parameters documentation (e.g., @param showNavigationIcon) no longer accurately reflects the code's logic or structure. (ArticleScreen.kt)

2. Use of deprecated icons
   Some icons used in the project, such as Icons.Filled.ArrowBack, have been deprecated in the latest Material icons package. These should be replaced with their updated AutoMirrored counterparts.

Describe the solution

1. Replace outdated @param descriptions like showNavigationIcon with accurate ones such as isExpandedScreen reflecting actual behavior.

2. Update deprecated icon usages by switching from Icons.Filled.* to Icons.AutoMirrored.Filled.* as recommended by Material guidelines.
