fix: 更新 test_1280 ASR跳过测试以匹配 PR #1294 的 voice_id 条件变更

从 main 分支 PR #1308 手动适配到 develop 分支，保留 develop 现有功能：

Schema 层：
- 新增 ConfirmGenerationRequest schema
- CreateGenerationTaskRequest 增加 6 个新字段（is_preview, source_task_id, output_width, output_height, cover_url, custom_title）
- GenerationTaskResponse 增加对应字段

Domain 层：
- GenerationTask 实体增加 source_task_id, output_width, output_height, cover_url, custom_title 字段
- create() 工厂方法增加对应参数

Application 层：
- CreateGenerationTaskCommand 增加对应字段
- UseCase 执行时传递新字段

DB 层：
- GenerationTaskModel 增加 5 个新列（is_preview 已存在于 develop）
- 仓储 _to_domain/create/update 映射更新

API 路由：
- 新增 POST /tasks/{task_id}/confirm 端点
- 使用 safe_enqueue_generation_task 适配 develop 任务入队机制
- 更新 _to_generation_task_response 和 retry 端点

Worker 层：
- _load_task_info 返回新字段
- generate_video 支持动态分辨率（output_width/output_height 覆盖默认分辨率）

Alembic 迁移 054：
- generation_tasks 表增加 source_task_id, output_width, output_height, cover_url, custom_title 列

单元测试：
- tests/unit/test_confirm_generation.py（7 个测试用例全部通过）
- 适配 develop 的 safe_enqueue_generation_task 入队机制
