Communication: Input area remains active for archived channels without refreshing

[asliayk]

Describe the bug

When a channel is archived, the input area should disappear to prevent users from sending messages. However, the input area remains active until the page is refreshed. If the user tries to send a message in the archived channel, an error message appears.

To Reproduce

1. Go to Communication section of a course
2. Open a channel
3. Archive the channel
4. Observe that the input area is still visible and usable
5. Try to send a message in the archived channel
6. Notice that an error occurs

Expected behavior

The input area should be removed immediately after the channel is archived, without requiring a page refresh, to prevent users from attempting to send messages.
