fix: copy projects/ directory into Docker builds

[gilesw]

Problem

The Docker build (docker-compose.build.yml) was failing because Dockerfile.build (and Dockerfile.build.yarn) never copied the projects/ directory into the build container. The @orcid/ui, @orcid/registry-ui, and @orcid/tokens libraries live under projects/ and are resolved via path mappings in tsconfig.json, so the Angular compiler couldn't find them:

Cannot find module '@orcid/ui' or its corresponding type declarations.

GitHub CI was unaffected because it checks out the full repo and builds directly on the filesystem — no Docker layer involved.

Fix

Added COPY ./projects ./projects to both Dockerfiles so the library source is available at build time:

• Dockerfile.build — added after COPY ./src ./src, before the mvn package step
• Dockerfile.build.yarn — added after COPY scripts/ scripts/, before RUN yarn build
