refactor: modernise RPM builder with Python tooling

- Replace Makefile version/release file system with metadata.yaml only
- Add Python build automation (./tools/build) with Gitea API integration
- Add GitHub release updater (./tools/update-gh) for version management
- Centralize Dockerfiles into single parameterized Dockerfile
- Remove 54+ individual package Dockerfiles and version directories
- Update Makefile to use new Python tooling
- Add GITEA_API_TOKEN validation to prevent duplicate builds
- Support both explicit version/release args and metadata.yaml reading
