fix(docker-dev): stamp the git commit into rig image versions via a SOURCE_REVISION build arg (#893)

.dockerignore keeps .git/ out of the build context, so the in-image publish had
no repository and AssemblyInformationalVersion (Telemetry service.version) was a
bare 1.0.0. The Dockerfile now takes ARG SOURCE_REVISION and passes it to
dotnet publish as SourceRevisionId; docker-compose.yml forwards it as a build arg
for the host and migrator images; the new docker-dev/compose.sh wrapper exports
git rev-parse HEAD (suffixed -dirty for an uncommitted tree; an explicit value
wins) and runs docker compose with the base file. Without the arg the build
still succeeds as 1.0.0. The ARG sits after restore so a new commit does not
bust the restore layer. Mirrors ScadaBridge 7e34d7c2 (ScadaBridge#134).

+# docker compose wrapper for the docker-dev rig that stamps the git commit into the images (#893).
+#
+# .dockerignore keeps .git/ out of the build context, so the in-image `dotnet publish` cannot read the
+# commit itself and AssemblyInformationalVersion would be a bare "1.0.0". This exports SOURCE_REVISION
+# (git rev-parse HEAD, suffixed "-dirty" for an uncommitted tree) for the compose `build.args`, which
+# the Dockerfile hands to the SDK as SourceRevisionId -> "1.0.0+<sha>". An explicit SOURCE_REVISION in
+# the environment wins; outside a git checkout it stays empty and the images stamp a bare "1.0.0".
+#
+# Usage (any docker compose arguments; the base compose file is always passed first):
+#   docker-dev/compose.sh up -d --build
+#   docker-dev/compose.sh -f docker-dev/docker-compose.questdb.yml up -d --build central-1 central-2
+#   docker-dev/compose.sh build central-1
