feat: stamp the build version into every service

Browse Source 
pkg/version.Version (default "dev") is set at link time via -ldflags from each
service Dockerfile's VERSION build-arg, which the deploy passes as the git tag
(git describe --tags). It surfaces as the OpenTelemetry service.version resource
attribute (so Grafana/Tempo are version-aware), alongside the SPA's existing
About version. Adds the VERSION build-arg to the backend/gateway/validator/bot
compose builds and a serviceResource test covering service.name + service.version.
