fix: add working-copies bind mount and replace repo_data volume

The workspace mount was failing because /data/working-copies/ was not
bind-mounted into the API container. The workspace management code writes
to /data/working-copies/ inside the API container, but tool instances
mount from the host filesystem. Without a shared bind mount, the host
saw an empty directory.

- docker-compose.yml: add /data/working-copies bind mount, replace repo_data
- docker-compose.traefik.yml: same changes
- Remove repo_data named volume declaration from both files
