[FEATURE] Unarchive conversation feature request

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

When I accidentally archive a conversation, there is no way to restore it back to the active list.
I can only view archived conversations by filtering, but cannot unarchive them.
This makes it frustrating when I archive a conversation by mistake or want to reactivate an old conversation.

Proposed Solution

Add an "Unarchive" button or option when hovering over archived conversations in the sidebar,
similar to how the "Archive" button appears on active conversations.
This would allow users to move conversations back from the archived list to the active list.
