Fix devcontainer configuration with ubuntu user for proper permissions

- Switch from custom vscode user to existing ubuntu user (UID 1000)
- Configure Oh My Zsh and Claude Code for ubuntu user
- Update docker-compose volume mounts to use ubuntu paths
- Add proper shell history and PATH configuration
- This should resolve shell history permission issues with Docker volumes
