feat: AI 智能查询改为可拖拽缩放的非模态浮窗并支持多行输入

- 统计面板与收支记录的 AI 智能查询由模态弹窗改为非模态浮窗，窗口打开时可继续操作主界面，无遮罩且不自动聚焦
- 新增通用浮窗组件 FloatingPanel，支持标题栏拖拽与右下角缩放，位置尺寸按页面持久化到 localStorage
- 新增 AiQueryWindow 组件，输入由单行改为多行文本域，Enter 换行、Ctrl/Cmd+Enter 提交
- 历史记录聚焦时以浮层展示并可按输入过滤，忽略大小写去重、最多保留 200 条
- 提交查询后不关闭窗口，移除取消按钮，统一由右上角关闭按钮关闭
- 修复示例下拉层级低于浮窗被遮挡的问题，并在打开窗口时重置加载状态，避免按钮一直显示加载中
- 补充 close 与 ai.query.submitHint 的中文、英文、日文三语文案
