fix: restyle pager chips and restore theme ad slots

Replace the loose page-count label with a SaBlog-style 6 / 316 chip, wire inject/stylevar HTML into list and post views, and flush page cache when ads are saved.

 ## Pagination and imported HTML
 
-- Public pagers use `onEachSide(1)` plus “第 x / y 页”, and the main column is CSS grid `minmax(0, 1fr)` so page chips stay in the content column.
+- Public pagers use `onEachSide(1)` plus a compact `6 / 316` chip (old SaBlog `.p_bar` look), and the main column is CSS grid `minmax(0, 1fr)` so page chips stay in the content column.
 - `SablogHtmlNormalizer` strips leftover `&nbsp;`, turns SyntaxHighlighter `codeText` / `dp-*` lists into `<pre><code>`, and wraps stacked docker/shell `<div>` lines.
 - Render path always normalizes, so already-imported posts look right without rewriting the database. Persist with `php artisan sablog:fix-content --all`.
 - Code blocks wrap / scroll inside the column instead of stretching the page.
 
+## Theme ads / inject

+- All list and post views include `content_top` / `content_bottom` (and post body) stacks. Saving **主题注入** flushes page cache.
+- Theme variables (old stylevars) render automatically: `ad_header` → header, leftover HTML vars such as `huangjinlian` → footer.
+- `sablog:import` now copies the old `stylevars` table into `theme_vars_{theme}`.
+- Do not add a third half-finished skin. Tighten `sablog` to match the old site; a new theme is a later, complete job.
