Introduces PgBouncer as a connection pooler between the API service and
PostgreSQL in docker-compose.prod.yml, reducing connection overhead and
improving concurrency under production load.
- Add PgBouncer service (edoburu/pgbouncer:1.23.1-p2) with transaction
pool mode, max_client_conn=200, default_pool_size=20
- Route API DATABASE_URL through PgBouncer (port 6432), keep direct
connection (DATABASE_URL_DIRECT) for Prisma migrations/introspection
- Create infra/pgbouncer/ config: pgbouncer.ini, userlist template,
and entrypoint script with runtime env-var substitution
- Update prisma.config.ts to prefer DATABASE_URL_DIRECT for migrations
- Add K6 load test (e2e/load/pgbouncer-pool-test.js) with ramp-up to
200 VUs, pool exhaustion detection, and p95 < 2s threshold
- Add PgBouncer env vars to .env.example

The env-validation module previously only checked that JWT_SECRET and
JWT_REFRESH_SECRET were _present_ — it accepted any value, including
known placeholders like "CHANGE_ME". This meant a developer could copy
.env.example verbatim and run the app with predictable, forgeable tokens.
Changes:
- Add FORBIDDEN_SECRET_VALUES blocklist (case-insensitive) with 23 common
placeholder strings (CHANGE_ME, secret, password, test, etc.)
- Enforce minimum 32-character length for JWT secrets (NIST HMAC guidance)
- Export validateJwtSecret() for direct testing and reuse
- Update .env.example: replace "CHANGE_ME" with generation instructions
- Add 14 unit tests covering placeholder rejection, length enforcement,
missing-var errors, and production-mode validation

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.
