feat(FR-2593): implement VFolder creation modal using V2 GraphQL mutation

Resolves #6755(FR-2593)

- Create FolderCreateModalV2.tsx using Relay useMutation with createVfolderV2
- Map form values to CreateVFolderV2Input (usageMode, projectId, permission, cloneable)
- Map V2 response (VFolder with nested metadata/accessControl/ownership) back to FolderCreationResponse for backward compatibility
- Keep useTanQuery for list_allowed_types() since no V2 equivalent exists
- Update all consumers to import FolderCreateModalV2
- Original FolderCreateModal.tsx left untouched per epic guidelines
