feat(helm): add environment variables for Reflex configuration

Changes:
- Add API_URL, FRONTEND_PORT, BACKEND_PORT env vars to deployment
- Construct DATABASE_URL from PostgreSQL connection params
- Construct REDIS_URL from Redis connection params (with/without password)
- Add reflex.apiUrl config to values files:
  * Default: http://localhost:8000
  * Staging: https://staging.peikarband.ir
  * Production: https://peikarband.ir
- Add ENVIRONMENT to configMap

This ensures rxconfig.py gets proper environment-specific configuration
without hardcoding values. The app now works correctly in all environments
(dev, staging, production) with appropriate URLs and settings.
