feat: 全面升级项目架构 - PostgreSQL迁移 + 配置化改造
主要变更: - 数据库: SQLite → PostgreSQL (yzr_nr) - 选题系统: 硬编码字段 → 配置化 (TopicField/TopicConfigField/TopicStatusConfig) - 新增模型: ContentCalendar, ContentMetrics, MediaAsset, PlatformConfig, ContentTask - 新增 API: topic-config, calendar, metrics, assets, tasks, platform-config - 数据迁移: 现有选题数据迁移到新 schema (field_id/tags/custom_data/scoring_data) - 初始化数据: 10个领域, 5种状态, 3个平台配置 服务运行: http://localhost:8001 默认账号: admin / admin123
