Dockerfile: fix broken docker build

[github-actions]

fixes #32100

Docker builds from master were broken in two places:

1. cmd/openapi/openapi.go was removed in API: generate /api/state documentation from UI types #31530 (replaced by the external tool github.com/evcc-io/openapi-mcp/cmd/openapi-mcp, now declared in go.mod's tool (...) block), but Dockerfile still had COPY cmd/openapi/ cmd/openapi/, referencing a directory that no longer exists. cmd/implement/ (still a local-module tool) remains copied as before.

2. make ui in the node stage runs npm run build, which since API: generate /api/state documentation from UI types #31530 also runs the openapi generator. That generator needs tsconfig.json, scripts/ and the server/*.yaml specs, none of which were copied into the node stage. They are now, together with an mkdir for the generator's server/mcp output folder.

Also added local tooling directories and *.db to .dockerignore to keep them out of the build context.

To be able to build the docker image, I had to made the following changes:
