chore: Remove production Docker infrastructure and reorganize docs

- Remove production Docker Compose files (docker-compose.production.yml, docker-compose.prod-simple.yml)
- Remove production Dockerfiles (backend and frontend)
- Move implementation docs to docs/implementation-docs/ directory
- Remove test scripts (test-embeddings.js, test-voice-*.js/sh)
- Update ecosystem.config.js with production environment variables (CORS, JWT secrets, database config)
- Add database connection pooling configuration
- Update CORS configuration for production domains (parentflowapp.com)
- Fix frontend dev server port configuration (3005)
- Add PWA web push implementation plan documentation
- Simplify health check endpoints (remove MongoDB/Redis specific checks)
