refactor: standardize Dockerfile and build script structure

Standardize all RPM packages to use a consistent build pattern:
- Simple Dockerfiles that copy resources/ and call build.sh
- Move all build logic to resources/build.sh scripts
- Consolidate nfpm.yaml and scripts into resources/ directory
- Update base image to almalinux9-rpmbuilder for consistency

Changes:
- Refactored 37 packages total (simple + complex)
- HashiCorp tools: consul, vault, terraform, terragrunt, packer, nomad, nomad-autoscaler
- Development tools: g10k, etcd, nfpm, ruff, uv, unrar, nzbget, boilerplate
- VictoriaMetrics: vlutils, vmutils, victoria-logs
- Network tools: cni-plugins, consul-cni, unkin-ca-certificates
- Jellyfin suite: jellyfin-web, jellyfin-server, jellyfin-ffmpeg-bin
- System packages: puppet-initial, incus

This standardization improves maintainability and consistency across
the entire RPM build system while preserving all existing functionality.
