iris d5009cd175 dashboard: add favicon (hyperhive mark)
The main dashboard had no favicon — PR #145 added them to the
per-agent pages but missed hive-c0re's index. Serve branding/
hyperhive.svg at /favicon.svg and declare it in the index head.
The dashboard represents the whole hive, so it uses the project
mark (per-agent pages keep their own configurable /icon).

closes #173
