Add complete OAuth2 authentication flow for Google and Zalo providers:
- OAuthService: handles account linking (by email/phone), new user
creation for OAuth-only accounts, and JWT token generation
- GoogleOAuthStrategy: passport-google-oauth20 integration
- ZaloOAuthStrategy: custom OAuth2 implementation using Zalo's API
(authorization URL generation, code exchange, user info fetch)
- OAuthController: redirect and callback endpoints for both providers
with httpOnly cookie-based token management
- Unit tests for OAuthService (7 tests), GoogleOAuthStrategy (4 tests),
and ZaloOAuthStrategy (7 tests)
- OAuth env vars added to .env.example and env-validation warnings

- Add startup env validation that fails fast in production if critical vars
(JWT_SECRET, JWT_REFRESH_SECRET, DATABASE_URL, CORS_ORIGINS, REDIS_HOST)
are missing
- Fix CORS_ORIGINS to throw in production instead of defaulting to localhost
- Replace hardcoded dev passwords in .env.example with CHANGE_ME placeholders
- Add missing vars to .env.example (CORS_ORIGINS, SMTP_*, FIREBASE, LOG_LEVEL)
- Warn on missing optional payment/storage vars at startup

The auth module fell back to a publicly-known secret string when JWT_SECRET
was unset, creating a critical authentication bypass risk. Both jwt.strategy.ts
and auth.module.ts now throw at startup if JWT_SECRET is missing.
