fix(gateway): 三处生产安全硬化(默认密钥/admin裸奔/CORS)
1) JWT 默认密钥:生产模式(APP_ENV=production|prod 或 GIN_MODE=release)下若未设 JWT_SECRET 直接 log.Fatal,杜绝用开发默认值签发可伪造令牌;开发期警告并放行。 2) /admin 运维控制面(含模型 API 密钥管理)改挂 RequireAdmin:必须登录 + (设了 ADMIN_USER_IDS 则)uid 须在白名单;生产期未配置管理员直接 403。 3) CORS Allow-Origin 由 CORS_ALLOW_ORIGIN 配置(缺省 * 仅开发),非 * 时加 Vary。 build + auth 单测通过。仍属"小范围灰度"级,TLS/可观测/集成测试/HA 见 PROGRESS。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
