fix: Usability issues in conversation card context menu (#10971)

# Pull Request Template

## Description

The PR includes usability feedback fixes for the conversation card
context menu. A "Mark as Read" option has been added after "Mark as
Unread" to prevent misclicks due to shifting menu positions.
Additionally, a separator line has been introduced for better grouping
and clarity
