fix(single): align author-bar publish time with the reference

The publish time under the author name diverged from the reference in four
ways: it rendered a leading bullet from `.icon-circle`, its tooltip opened
above instead of below, its wording was "2 天发布" (WordPress'
human_time_diff has no 前 and keeps spaces), and it ignored the
「时间显示数据源」 setting entirely.

- markup: drop `.icon-circle` from the time span and the description fallback;
  add `data-placement="bottom"` so the tooltip opens below like the reference
- wording: use jio_time_ago() (which already ends in 前) and append only
  发布 / 更新, yielding "2天前发布"
- branches: mirror zib_get_post_time_tooltip exactly (date source → publish
  time; unpublished → modified time; published-with-update → modified time
  labelled 更新 while the tooltip keeps the publish time; otherwise publish)
- the setting is read from post_time_source via get_post_list_style_settings()

Tests: new author-bar-time suite drives the real template through a stub
harness across all four branches (4/4); widget suite 833/834 with the
pre-existing frontend-lifecycle failure.
