fix: declutter today view and task rows

- Drop redundant <h2> page titles in 习惯 / 倒数日 / 设置与数据
- Wrap today view in three <section class='today-block'> sub-blocks:
  今日任务 / 今日习惯 / 倒数日提醒 (7 天内 countdowns)
- Reduce task row noise: priority becomes a colored dot, priority
  select and priority-text removed; delete action is desktop-only
- Hide task row inline actions and pager when only a single page
- Add a row-level More menu on sidebar list / folder rows (rename,
  archive, delete) and a 'archived' toggle that appears only when
  archived lists exist
- Add 'archived-heading' / 'page-subtitle' / 'today-block' /
  'priority-dot' / 'task-delete{display:none}' / 'row-menu' styles
  and a mobile 'min-height:44px' hit area for sidebar row actions
- Refresh unit tests in src/style.test.ts to cover the cleanup
