feat(toolset): 工具系统重构为 toolset 统一管理，新增系统预置工具集

将工具管理从"agent 挂单个 tool"改为"agent 挂 toolset"模式：
- 三个系统预置工具集（system_basic/system_chat/system_workflow）入 DB
- 新增 send_file 工具（系统对话工具集）、修复 approval actor 调用 bug
- 后端 agent 加载全部走 toolset 链路，移除 load_tools_from_list
- 前端工具集中心卡片展示 + agent 配置改为 toolset 多选
- resource API 增加 category 过滤与系统 toolset 保护
