Removes dashboard feature flag

[Mbeaulne]

Description

The Dashboard feature flag has been promoted out of beta and is now the default experience. The dashboard feature flag has been removed entirely, along with the legacy Home route and its associated components (PipelineSection, RunSection). The DashboardLayout is now always rendered unconditionally, and the Beta badge has been removed from the Dashboard sidebar heading. The FavoriteToggle component no longer gates its rendering behind the dashboard flag.
