feat(config): improve security and add WhiteNoise static file serving

**Security Improvements:**
- Fix DEBUG setting to properly parse boolean from environment variable
- Remove hardcoded SMTP password fallback, rely solely on env var
- Update Celery to use REDIS_URL environment variable instead of hardcoded localhost

**Static File Serving:**
- Add WhiteNoise middleware for production-grade static file serving
- Configure CompressedManifestStaticFilesStorage for optimized delivery

**Configuration Updates:**
- Enable CORS credentials support
- Remove duplicate CORS_ALLOWED_ORIGINS configuration
- Update API documentation title from "Blog API" to "Attune Heart Therapy API"
- Clean up code formatting and remove unnecessary comments

These changes make the application more secure by eliminating hardcoded
credentials and more deployment-ready by properly handling environment
variables and serving static files efficiently in production.
