build(deploy): replace pre-compiled arm64 binaries with multi-stage Go compilation for amd64

WHY: existing Dockerfiles copied pre-compiled arm64 binaries which cannot
run on the amd64 K3s cluster (exec format error). Also fixed port conflicts
when running muyu alongside iloom in docker-compose.

HOW:
- rewrite 3 Dockerfiles (system/inventory/gateway) to multi-stage builds
  using golang:1.24-alpine with CGO_ENABLED=0 GOARCH=amd64
- parameterize host ports in docker-compose to avoid conflicts (3306->13306,
  6379->16379, 8080->18080)
- fix inv_product unique key from product_name-only to composite
  (product_name, spec, color) to allow same-name products with different specs
- add X-Token to Authorization header middleware in gateway for
  iloom frontend compatibility
