fix: 日报摘要可靠性(去模型兜底+重试) 与取数逻辑优化

Browse Source 
- llm/client: 移除内置默认模型兜底(deepseek-chat/qwen-plus), 模型必须显式配置否则报错
- reporter._llm_call: 指数退避重试(LLM_RETRY_TIMES 默认3 / LLM_RETRY_BACKOFF_SEC 默认2s)
- pipeline report: report_date 改为当天(原昨天+回溯3天)
- reporter._collect_news_events: 读当天+前一天目录, publish_time 30h 回溯(NEWS_LOOKBACK_HOURS=30), 统一时区
- reporter._collect_xwlb: 固定取 day_str 前一日(已播出联播), source_date 同步
- 公告/调研/互动保持近15日设置(CNINFO_DAYS_BACK), 不受 30h 影响
- 测试: 新增 30h回溯/带时区/重试/模型缺失/xwlb 前一日 用例
