Room Avatar Change Does Not Sync with Sidebar

Description:

When updating a room/channel avatar, the new avatar does not reflect immediately in the sidebar. The room header and room info panel update correctly, but the sidebar continues to show the old avatar until a page refresh or re-entering the room.

Steps to reproduce:

1. Open any room/channel.
2. Click Channel Info → Edit → Upload Avatar.
3. Select any image and save.

Observe:
Room avatar updates successfully in the room info panel.
Sidebar avatar remains the old avatar.

Expected behavior:

The new room avatar should update simultaneously in all UI locations, including the sidebar.
No manual refresh should be required.

Actual behavior:
Room avatar updates in the header and room info panel.
Sidebar avatar does not update immediately.
