feat: sase.tr v2 full application implementation

Complete rewrite of sase.tr VIN lookup platform with modern stack:

Backend (NestJS 10 + Drizzle ORM + PostgreSQL + Redis + BullMQ):
- 34 DB models (core + PL24 + EMEX schemas)
- Auth via Better Auth (email/password + social)
- Brands, Plans, Subscriptions, Payments (iyzico + EFT)
- VIN decode orchestration (Corgi + PL24 + EMEX + NHTSA)
- Interactive schema viewer backend (MinIO storage)
- EMEX scraping integration (Puppeteer + BullMQ workers)
- Translation module (EN→TR automotive dictionary)
- Admin dashboard API (stats, user mgmt, payment approval)
- Rate limiting, Helmet security, file upload validation

Frontend (Next.js 15 + Tailwind v4 + shadcn/ui + TanStack Query + Zustand):
- 20 routes: auth, dashboard, VIN search, schema viewer, admin
- Interactive schema viewer with zoom/pan/hotspot highlighting
- Subscription management with brand selector
- Payment flow (iyzico 3D Secure + EFT with receipt upload)
- i18n support (TR/EN)
- Error boundaries, loading skeletons, 404 page

Infrastructure:
- 85 tests (52 backend + 33 frontend, Vitest)
- CI/CD (GitHub Actions: lint, typecheck, test, build, deploy)
- Zero-downtime deploy script (PM2)
- Env validation script
