fix: Object.values null safety + Docker dev build

- Change Dockerfile to use development build (better error messages)
- Add || {} fallbacks to all Object.values() calls accessing state
- Fixes "Cannot convert undefined or null to object" browser error during SSR/hydration
- Verified TypeScript compilation and Next.js build successful
