fix: optimize Dockerfile to use Yarn PnP instead of node-modules

Browse Source 
- Use Yarn Plug'n'Play (PnP) for faster installs and smaller image size
- Keep .yarnrc.yml configuration instead of overriding it
- Copy PnP files (.pnp.cjs, .pnp.loader.mjs, .yarn cache) to production stage
- Use yarn workspaces focus --production for production dependencies
- Corepack manages Yarn version while PnP handles dependency resolution
