Pull request overview

This PR changes the persistence mechanism for resource collapsed state from session storage to local storage, enabling the collapsed state to persist across dashboard sessions. It introduces application-specific storage keys and adds replica index tracking to resources for stable identification across app host restarts.

Key Changes

• Storage migration: Collapsed state now persists in local storage instead of session storage, scoped per application name
• Replica tracking: Resources now have a ReplicaIndex property to distinguish between replicas of the same resource
• Persistent keys: Resources use DisplayName_ReplicaIndex as a persistent key instead of the resource name (which contains random suffixes)
