chore: improve Docker/Podman compatibility and package installation

- Update Claude permissions to allow podman-compose commands
- Improve Dockerfile package installation with poetry-core
- Switch to explicit docker.io image references for Podman compatibility
- Add PYTHONPATH configuration to ensure proper module imports
- Change frontend port from 80 to 8080 for non-root compatibility
- Add initial chat server implementation (main.py)
