Products were inserted with empty tenant_id because ExtractTenantId was
called after the Insert; moved extraction before the struct so rows are
stored with the correct tenant and appear in list queries.
Regenerated purchase.pb.go and purchase_grpc.pb.go from purchase.proto
using protoc-gen-go v1.36.11; the previous hand-written stubs lacked the
proto.Message interface, causing all purchase gRPC calls to fail with a
marshal error.
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).
