feat: disable Workflow, Calendar in production (dev only)

Added feature flags to conditionally disable experimental features:
- ENABLE_WORKFLOW: Workflow blocks (dev only)
- ENABLE_CALENDAR: Calendar shape/tool (dev only)
- Drawfast was already disabled

These features will only appear in development builds.
