refactor: 将 A_Memorix 重构为主线长期记忆子系统并重建管理界面

- 将 A_Memorix 从旧 submodule / 插件形态迁入主线源码，主体落到 src/A_memorix
- 调整主程序接入方式，使 A_Memorix 作为源码内长期记忆子系统运行
- 回收父项目插件体系中针对 A_Memorix 的特判，减少对 plugin 通用层的侵入
- 将长期记忆配置、运行时、自检、导入、调优等能力收口到 memory 路由与主线服务层
- 重做长期记忆控制台与图谱页面，按 MaiBot 现有 dashboard 风格接入
- 补充实体关系图与证据视图双视图能力，支持查看节点、关系、段落及其证据链路
- 新增长期记忆配置编辑器与 memory-api，支持主线内配置管理
- 补齐删除管理能力：删除预览、混合删除、来源批量删除、删除操作恢复
- 优化删除预览与删除操作详情的前端展示，支持分页、检索，并以实体名/关系内容/段落摘要替代单纯 hash 展示
- 修复图谱与控制台相关前端问题，包括证据视图切换、查询触发时机、删除弹层空值保护等
- 新增或更新 A_Memorix 相关测试、WebUI 路由测试、前端 vitest 测试与辅助验证脚本
- 移除旧 plugins/A_memorix、.gitmodules 及相关历史维护文档
