新增智能体收藏、定时任务必须生成MD校验、问答时间显示及账号绑定的常用提示词

- 智能体支持从广场收藏到「我的」（新增 agent_favorites 表与收藏/取消收藏接口）
- 定时任务新增「必须生成Markdown文件」开关：注入提示词并校验生成的 .md 文件且正文超过100字，否则记为失败（存于 execution_context，无需迁移）
- 聊天问答展示时间（年月日 时分）：问题在右下角、回答在左下角
- 常用提示词改为与账号绑定（新增 user_custom_prompts 表与 /api/user-prompts 接口），仅在首页输入框上方以居中标签 + 轮播展示，齿轮置于最右侧管理
