修复: aichat advance_task渲染显任务名 + 审批防双击 + time.ts销账

- UX-260618-14: advance_task 工具结果/审批卡显任务名替代UUID
  前端 ToolCard 取 r.title fallback r.id + TASK_ID_TOOL_ARG 审批卡 task_id→title 回显 + i18n
  后端 audit resolve_task_label 查 tasks 表(原误查 projects恒报不存在) + 删 tool_display_hint 短路让模板生效
- UX-260618-16: time.ts formatDate .value 已修(CR-24/25闭环),漏销账补登
- UX-260618-17: ProjectDetail handleApprovalMulti 补 submitting try/finally + 模板联动防双击
