Add a favicon-sized status indicator to the page title

[RaymondAbiola]

Summary

A user watching a stream often has the tab in the background. Reflecting the stream status in the document title lets them see at a glance whether anything has changed without switching tabs.

Acceptance criteria

• The document title reflects the state of the stream being viewed.
• The title reverts when navigating away.
• The change does not interfere with existing metadata.
