/**
 * OAuth Callback Handler
 *
 * Handles the OAuth 2.0 callback from the provider by:
 * 1. Validating the state parameter to prevent CSRF attacks
 * 2. Exchanging the authorization code for an access token
 * 3. Fetching the user profile from the provider
 * 4. Calling the onAuthSuccess callback to create/link user and generate JWT token
 * 5. Optionally storing the OAuth connection (if storeTokens enabled)
 * 6. Returning the JWT token to the client (via JSON or redirect)
 *
 * Route: GET /oauth/:provider/callback?code=...&state=...&response_type=json
