fix(admin/posts): 重建结果消息改为独立行，修复悬浮溢出表格的错位
RebuildCacheBar 的「已重建 X 篇文章」结果消息原用 absolute top-full mt-2 悬挂在按钮行下方，但 mt-2(8px) + text-sm(20px) = 28px 大于外层 space-y-6 的 24px 间距，消息底边向下溢出 4px 侵入表格容器上沿；横向 left-0 又使消息 落在右上角按钮组正下方、覆盖状态/日期/操作列，语义位置错位。 将 rebuilding / rebuild_result 状态上提到 PostsPage： - 结果消息在 header 与表格之间独立成行，进入文档流，吃 space-y-6 正常间距， 既不撑高 header 触发 items-center 重排（曾用 absolute 规避的旧问题）， 也不脱离流溢进表格（absolute 引入的新问题）。 - RebuildCacheBar 改为接收父级 Signal props，只渲染按钮行本身。
