Subject: [PATCH] fix(build): download protoc matching target arch in images

The three service Dockerfiles always fetched the linux-x86_64 protoc
release, so the build-time proto regeneration failed on ARM64 image
builds (protoc: No such file or directory, exit 127). Select the protoc
asset (x86_64 / aarch_64) from $(uname -m) so all target platforms build.
