Model selector is not clickable for agents on a headless server

When viewing an agent running on a headless AgentsRoom service from another desktop, the provider/model label in its header cannot be selected. This prevents opening Switch Provider to change the running agent's model.

Steps:

1. Run AgentsRoom with --server on a headless Linux host.
2. Start an agent on that host.
3. Open its remote console from another desktop.
4. Try to click the provider/model label in the console header.

Expected: Open the model/provider selector and apply the change on the host, preserving context according to the chosen transfer mode. Actual: The label is not interactive.

Viewer version: 1.268.0 on macOS. Headless host version not yet checked. Inspection of the installed viewer confirms that the local header supplies a model-picker handler, while the remote header does not. No matching existing report was found.
