Update Helm chart to use unified app image (API + Frontend)

Changes:
- Replaced separate api and frontend deployments with single unified app deployment
- Updated values.yaml: Changed from api/frontend configs to single app config
- Renamed templates: api-deployment.yaml → app-deployment.yaml
- Removed frontend-deployment.yaml and frontend-service.yaml (no longer needed)
- Updated app image to warehouse13/app (multi-stage Docker build)
- Combined resource allocations: 384Mi memory, 350m CPU (up from separate totals)
- Updated all example values files (dev, production, air-gapped)
- Updated NOTES.txt to reflect single service on port 8000
- Updated ingress to route all traffic to single app service
- Added ARCHITECTURE.md documenting the unified container approach

Architecture:
The application now uses a multi-stage Docker build:
1. Stage 1: Builds Angular frontend with Node
2. Stage 2: Python FastAPI backend that serves static frontend from /static

Benefits:
- Simplified deployment (1 container instead of 2)
- Reduced resource usage (no separate nginx)
- Easier scaling (1 deployment to manage)
- Consistent versioning (frontend/backend always match)

Access pattern:
- http://localhost:8000     → Angular frontend
- http://localhost:8000/api → FastAPI REST API
- http://localhost:8000/docs → API documentation
- http://localhost:8000/health → Health check
