- Add { algorithms: ['HS256'] } to all jwt.verify() calls to prevent
algorithm confusion attacks (including the 'none' algorithm)
- Add { algorithm: 'HS256' } to all jwt.sign() calls for consistency
- Reduce OIDC token payload to only { id } (was leaking username, email, role)
- Validate OIDC redirect URI against APP_URL env var when configured
- Add startup warning when JWT_SECRET is auto-generated
