Closes #55287

This fixes the SSH remote case where restarting a language server left a
stale entry in the LSP Logs panel.

The root cause was that the remote client learned about the replacement
language server, but never received an explicit removal update for the
previous server id. As a result, the old status and log-store entry
remained visible even though only the new server continued producing
logs.

Tested with:
- `cargo test -p collab --test collab_tests
remote_editing_collaboration_tests::test_ssh_restarting_language_server_replaces_remote_status
-- --exact`

Release Notes:

- Fixed stale duplicate entries in the LSP Logs panel after restarting
an SSH remote language server.
