fix(worker): 收敛异步重准入到调度器

准入租约失效时 Worker 仅释放执行准备并短暂让出 River 槽位，由异步调度器统一恢复 waiting 或无有效租约的任务，避免多 Worker 同时争抢全局容量锁并放大数据库同步提交等待。\n\n调度扫描覆盖到期且可运行的 scheduled/available/retryable River 任务，但跳过正在执行或仍持有有效准入租约的任务；新增 PostgreSQL/River 状态集成回归测试。\n\n验证：Go 全量测试、go vet、runner/store race、gofmt、迁移安全检查通过；专用数据库集成用例因本机未配置 AI_GATEWAY_TEST_DATABASE_URL 明确跳过。
