feat(ui): render the Contacts panel from the awareness layer's published view

The awareness layer presents its panel as a plain view and publishes it through subscribePanel() instead of writing markup into #military-awareness-panel. AwarenessPanel renders it from the gev-context store, calls the layer's navigation, and keeps focus on the same control by identity across live repaints, continuing at the note when that control leaves or is disabled.
