fix: use Next.js standalone output for Azure deployment

Switch from zipping cf-webapp/node_modules to Next.js standalone output
mode. This traces only required runtime deps into .next/standalone/ and
resolves the pnpm symlink issues that caused MODULE_NOT_FOUND crashes on
Azure (missing @next/env, @swc/helpers).

- Add output: "standalone" and outputFileTracingRoot to next.config.mjs
- Update CI to cp -rL (dereference symlinks) the standalone output
- Revert node-linker=hoisted from .npmrc (no longer needed)
- Deploy to codeflash-webapp-main (set in previous commit)
