feat(lifelog/photolog): 人物升为底部第一个 tab + 最近联系人置顶

- 「人物」从相册子页提升为**独立一级 tab，放第一位**（默认打开）；PhotologTab 拆成 ContactsTab(通讯录+档案) 与 AlbumTab(照片)，共用同一 PhotologViewModel(Activity 域) - 通讯录排序：点过/绑过声纹的联系人 lastAccess 置顶到「★ 最近联系人」区，其余仍按拼音 A–Z（Person.lastAccess 字段 + 迁移 v9→v10；点开档案/绑声纹时 touch）注：本提交还顺带含时间轴「按 5min 静音切时间段分组」的并行改动（同文件耦合，已编译通过）。实测：默认进人物页(共 4357)，点联系人后回列表，顶部出现「最近联系人」；迁移 v10 零数据损失。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
