Collapse the `/ccp-ovis` slash-redirect and prefix-strip flow into one `ovis-frontend-ccp` router by attaching both middlewares in order (redirect, then strip). This removes redundant router labels while preserving canonical `/ccp-ovis -> /ccp-ovis/` behavior and mounted-path forwarding to the frontend service.
Apply the PR #375 review feedback by removing Bridgehead-specific compose/setup overrides
that duplicated upstream OVIS behavior and by switching to the upstream-built Mongo image
that already contains init logic.
- rename CCP OVIS services to consistent upstream-style names (`ovis-*`) and update internal dependencies
- switch Mongo service image from direct `mongo:latest` + host-mounted init script to `docker.verbis.dkfz.de/ovis/ovis-backend-mongodb:latest`
- remove obsolete Mongo init bind mount (`/docker-entrypoint-initdb.d/init.js`) from compose
- drop redundant runtime overrides from compose (`restart`, `command`, `user`, `working_dir`)
- remove duplicated app-default/preprocessor env overrides (`OVIS_PREPROC_*`, misc backend defaults) and keep deployment wiring only
- fix Mongo connection env usage to `ADDRESS` and point services to `ovis-backend-database-mongodb`
- remove temporary root-compat Traefik redirect shim and keep mounted `/ccp-ovis` routing labels
- remove setup-time generation of Mongo init.js and related cache directory prep from `ccp/modules/ovis-setup.sh`
- Replaced GUI_HOST with HOST
- Removed NODE_ENV
- Combine init_onco and backend service
- removed node_modules and .svelte-kit volumes
- removed mongodb volumes
- adjusted http_proxy and https_proxy
- adjusted path prefix from oaut2 to oauth2-ovis
- removed network-mode "host" in fhir-transformer service
- Removed the traefik service and renamed traefik-forward-auth to ovis- with ovis-traefik-forward-auth the labels, however would need help there as i got no knowledge of how OAuth2 works (Torben initialized that container)
- Updated MongoDB service configuration to include a direct initialization script for user and operation collections in the sh instead of in the compose directly
- Adjusted volume paths to only use the /var/cache/bridgehead/ccp directory
- Adjusted frontend and backend service labels for Traefik routing to not use ports
- Cleaned up unnecessary network definitions and volumes.
- Renamed FHIR Server URL to bridgehead-ccp-blaze:8080/fhir
- Removed redundant entrypoint (python main.py) of fhir transformer
