fix: resolve Calendar identifier conflict in DynamicPropertiesPanel

- Rename Calendar import from lucide-react to CalendarIcon2 to avoid
  conflict with Calendar from @/components/ui/calendar
- Add tsc --noEmit and pnpm build steps to CI to catch type/bundler
  errors before tests run (prevents this class of bug from reaching main)
