fix: auto-save draft + API cleanup for editing flow (PR #1465)

- Step2/Step4 auto-save via useDraftAutoSave (GET-merge-PUT, serial queue)
- useDraftAutoSave: failed saves preserve patch with exponential backoff retry
- Step6 cover requests include full title_config
- Step7 create task: source_edit_plan_id, title_config, cover_url priority
- Polling switched to GET /generation/tasks/{task_id} with proper error handling
- getGenerationTaskResults retries before treating as failure
- Removed 7 ghost API functions (non-existent backend routes)
- BGM presets path updated to /templates/{id}/editor/bgm/presets
- Type alignment for BatchGenerationTaskResponse
