refactor: unify path management and complete profile management system

- Create internal/paths package for unified config and runtime directory resolution
- Implement robust WireGuard config parsing in pkg/wgconf
- Implement profile management subcommands: list, import, configure, delete, stop
- Fix namespace pinning path collisions (separating .ns files from pids directories)
- Implement and verify namespace unpinning logic
- Fix linting errors and improve error handling across the project
