mrhid6 ee1f9f3b32 refactor: consume vantage-shared as an external private module
shared/ is extracted to gitea.hostxtra.co.uk/vantage/vantage-shared and
pinned at v0.1.0 by server, agent, admin, sitesvc and vantagectl. The
replace directives and the ./shared entry in go.work are gone.

Every Go build now needs a credential for the private module: CI writes a
netrc per job from REGISTRY_USER + RELEASE_TOKEN and sets GOPRIVATE, and
the four Go Dockerfiles take it as a BuildKit secret rather than a build
arg, which would survive in the builder layer's history. RELEASE_TOKEN
needs read access to the vantage org.

admin, sitesvc and vantagectl now build from their own directory; only
server still needs the repository root, for default_steps/. The rebuild
triggers in server-deploy.yml lose their shared/ patterns, since a
service now moves when its own go.mod pin does.

# Context is admin/ itself. It used to be the repository root, so that
# shared/ could be copied in beside it; shared is now the private module
# gitea.hostxtra.co.uk/vantage/vantage-shared, fetched like any other
# dependency. The credential for it arrives as a BuildKit secret rather than a
# build arg, which would be baked into this stage's layer history.
