Describe the bug
Running openremote/manager:latest with the provided docker-compose.yml fails to serve the web UI at http://localhost:8080/manager (404 "Not Found"). The Manager API works (/api/server/info), but the web interface is missing.
The Dockerfile expects /opt/web folder containing the compiled UI assets, but this folder is not included in the published Docker image.

To Reproduce
Use the official docker-compose.yml from the Quick Start guide
Run docker-compose up
Navigate to http://localhost:8080/manager
Result: "Not Found" error

Expected behavior
The Manager UI should be accessible and fully functional.
Root cause
The Dockerfile has ADD web /opt/web, but the /web folder is never created during the Docker image build. The UI build process (yarn in /ui/app/) generates /dist, which should be packaged into the manager image, but this step is missing from the build pipeline.

Additional context
Proxy container fails on Windows/Podman (permission denied 80/443)
Manager is otherwise functional (API responds, database works)
Docker image appears to be a partial/incomplete build

This makes the official Quick Start guide non-functional for users without a working proxy setup.
