feat(all): 数据库模块化拆分与版本化迁移、任务引擎命名体系收敛、物理输出校验加固与用户配置接通

- server/db: 拆 4929 行 db.rs 单体为 db/ 目录，migrations.rs 引入 PRAGMA user_version
    版本化迁移运行器（M1~M13）
  - 任务引擎 Phase 6/7b/7c 改名收敛：EngineStageConfig→PhaseConfig、StagePolicy→ResumePolicy、
    Converged→Completed、删除 task_type 列、success_method 拆 tlusty_/synspec_ 双列、
    新增 tlusty_status/synspec_status 半失败阶段守卫
  - 科学正确性加固：conv_check 任意行 NaN/Inf/溢出判无效（0 行容忍）、新增 spec_is_valid
    校验 SYNSPEC 脏谱、itek_history 逐次迭代全量保真、fmt_abn powf 溢出饱和
  - 用户配置真正接通：tlusty_chain/tlusty_input 由死字段经 调度器→TaskSpec→executor→runner
    透传生效；config 加载期 validate + deny_unknown_fields + 解析失败记 warn
  - 调度修复：H1 活锁（pending_strategies 跳过已失败策略）、种子查找错误不再静默降级冷启动
  - dashboard: 阶段配置面板 tlusty_stage/synspec_stage、"已完成"标签、迭代诊断展示
  - docs: 新增 database_refactor_design.md，同步 database/api/PIPELINE/workflow_detail
