Previous fix copied packages/shared/node_modules and
packages/db/node_modules into the runtime stage, but pnpm's layout
makes those entries SYMLINKS into /app/node_modules/.pnpm/<dep>@<ver>/
node_modules/<dep> where the real package files live. Without
.pnpm/ in the runtime image, every symlink dangled and require
still threw 'Cannot find module rrule'.
Add a third COPY for /app/node_modules/.pnpm. Use --link so the
docker layer storage deduplicates against the build layer.
Same root cause class for any pnpm-managed monorepo deploy: ship
.pnpm/ together with the leaf node_modules dirs that point into it.
