Add self-hosted SubQuery node with @pezkuwi aliases

- Custom Dockerfile.node that aliases @polkadot/* to @pezkuwi/* packages
- Updated docker-compose.yml to build custom node image
- Added chainTypes/pezkuwi.json with Pezkuwi type definitions
- Updated pezkuwi.yaml manifest with chaintypes reference
- Added @subql/common-substrate dependency

This allows running SubQuery node with Pezkuwi chain recognition
instead of showing "Unknown Network" error.
