feat: 任务队列限流防护 - 用户级3个/全局20个

实现3层队列防护，防止批量提交导致队列爆炸：

**用户级限流（核心）**
- 每个用户同时 pending 的 generation 任务上限 3 个
- 超限返回 429：您的待处理任务过多，请等待完成后再提交

**全局限流（兜底）**
- 系统 pending 任务超过 20 个一律拒绝
- 返回 503：系统繁忙，请稍后再试

**覆盖的入口**
- 一键生成（generation_tasks 批量创建 + 重试）
- 剪辑计划生成（edit_plans generate）
- 任务中心重试（task_center 用户级 + 项目级）

**实现细节**
- 预检查 + 入队前检查双重保障
- 限流拒绝时任务标记为 failed，避免 pending 僵尸
- repository 不支持计数时自动降级跳过（兼容旧代码）
- 全局检查始终生效，用户级检查需传 user_id

**新增**
- task_enqueue.py: UserPendingLimitExceeded / GlobalQueueFull 异常
- generation_task_repository: count_pending_by_user / count_pending_total
- 13个单元测试，覆盖正常/超限/全局/降级等场景
