fix: docker build - use root context for monorepo workspaces

- Change build context from ./frontend|backend to root (.)
- Update Dockerfiles to copy from correct paths
- Use npm install instead of npm ci (workspaces share root lockfile)
- Remove obsolete version attribute from docker-compose.yml

Fixes npm ci errors when package-lock.json is at workspace root.
