Align origin/main with upstream/main (GitHub). The two branches diverged due to pre-rebase vs post-rebase merge commits for the k8s-amd64-dockerfiles feature. Includes: multi-stage Go compilation Dockerfiles, pan-bolt inventory features, CRM relations, Excel import tooling, proto/gRPC updates, migration scripts, and tools/ directory. Excludes deploy/bin/ pre-compiled binaries (arm64, not needed for amd64 K3s cluster; builds use multi-stage Dockerfiles now).
