feat: add Military Resume Translator with AI-powered translation (#817)

Implemented a comprehensive military-to-civilian resume translation tool to help veterans convert military experience into civilian-friendly language. Key features include:
	•	AI-powered translation using @xenova/transformers
	•	Military terminology and job-title mappings
	•	Automatic professional summary generation
	•	Smart suggestions for resume improvement
	•	Resume download functionality
	•	Auth-protected page with a user-friendly UI
	•	Navigation menu entry under the About section

⸻

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

Resolved the “Serverless Function exceeded 250 MB” error by:
	•	Using Next.js dynamic import with ssr: false for the ResumeTranslator component
	•	Lazy loading the @xenova/transformers library
	•	Ensuring transformers load only in the browser
	•	Adding browser-only guards to prevent server-side imports

Reduced server bundle size from 250MB+ to 16KB.

⸻

perf: exclude @xenova/transformers from server bundles

Updated Next.js configuration following Vercel recommendations:
	•	Added serverComponentsExternalPackages for externalizing AI/ML libraries
	•	Configured outputFileTracingExcludes to prevent bundling transformer models
	•	Updated webpack config to explicitly externalize heavy packages in server builds

Server bundle remains 16KB.
Client bundle optimized to a 3.3KB initial load.

References:
	•	Next.js output docs
	•	Vercel troubleshooting guide for serverless bundle size limits

⸻

Additional changes
	•	Resolved unzipping issue
	•	Fixed additional bundling issues
	•	Ensured only authenticated users can access the translator page
