Make release image tags truly immutable

 - Hardened the all-in-one release path with commit-SHA image tags, OCI build
   labels, previous-image preservation, automatic/manual rollback, an isolated
   fresh-install smoke and dependency-cache-safe build metadata.
+- Bound immutable release tags to both commit and dependency profile
+  (`<sha>-ai` or `<sha>-gis`) and reuse matching images instead of rebuilding
+  or overwriting an existing release tag.
 - Made production startup reject known-default PostGIS passwords and apply the
   configured upload limit consistently to nginx and FastAPI.
