chore: use getEnv in oauth module for platform agnosticity

[serhalp]

We'd like to avoid hardcoding platform-specific logic and assumptions in this codebase. We'll eventually add documentation for zero-config deployment to any platform.

btw, ideally I'd like to migrate all of this logic upstream to https://github.com/unjs/std-env so we simply have to import from it.

and we can support far more than just netlify or vercel platforms there.

📝 Walkthrough

Walkthrough

The PR adds environment URL helpers and integrates them into the OAuth Nuxt module. config/env.ts now exports isProduction, getPreviewUrl() and getProductionUrl(), changes isPreview logic to treat any non-production CONTEXT as preview, and extends getEnv() to include previewUrl and productionUrl. modules/oauth.ts changes setup() to be async, calls getEnv() instead of reading process.env directly, and selects clientUri from the derived URLs. Unit tests for the URL-resolution functions are added and an example test file was removed.
