Remove unused classes and properties related to Twingraph.

Deleted Twingraph-related event classes and unused properties (`images`, `containers`) from `CsmPlatformProperties`. Also added an `enabled` flag to `CsmStorage` for internal storage configuration. This simplifies the codebase and improves clarity.
