fix(manadeck): resolve backend startup and auth configuration issues

- Add missing env vars to generate-env script (DATABASE_URL, MANA_SERVICE_URL, APP_ID)
- Fix auth endpoints to use correct mana-core-auth paths (/api/v1/auth/login)
- Fix api.controller.ts to use getBalance() and completedAt field names
- Add SSR/optimizeDeps config for shared packages in vite.config.ts
- Remove outdated tailwind.config.js (conflicts with Tailwind CSS 4)
