Fix Docker build: compile TypeScript packages before runtime stage

The API Docker image was copying raw .ts source files for @groombook/db
and @groombook/types into the runtime stage, but tsx (the TS loader) is
a devDependency stripped by --prod install. Node.js cannot load .ts files
natively, causing ERR_UNKNOWN_FILE_EXTENSION at startup.

- Add build scripts to db and types packages
- Add outDir to types tsconfig
- Update package.json main fields to point to compiled dist/
- Build packages in dependency order in Dockerfile
- Copy only dist output to runtime stage
