配置全面迁移数据库：PromptConfig、TaskConfig动态调度、敏感词/清洗规则/趋势映射/平台标签/痛点模板全部可编辑

- 新增 PromptConfig 模型 + API，支持提示词在线编辑（16条默认）
- 调度器动态读取 TaskConfig.schedule，admin 可调执行时间
- 新增 KeywordDomainMap、SensitiveWord、ContentCleanRule、TrendFieldMapping 表
- DOMAINS、TREND_DOMAIN_MAP、PLATFORM_TAGS、china_pains、RSS关键词、priority_weights 全部迁移到 DB
- tasks.html 重构：卡片网格+配置/产出/历史/提示词四个Tab，折叠显示
- 清理冗余代码：DEFAULT_PROMPTS死代码、collector.py unreachable代码、compliance_checker bug
- strip_thinking_html 改用 DB 规则优先
