fix: prevent @xenova/transformers from bundling in serverless functions

Resolve "Serverless Function exceeded 250 MB" error by:
- Using Next.js dynamic import with ssr:false for ResumeTranslator component
- Implementing lazy loading for @xenova/transformers library
- Ensuring transformer module only loads client-side in browser
- Added browser-only check to prevent server-side imports

Server bundle size reduced from 250MB+ to 16KB
