feat(forum/shop): phase 6 dynamic page sidebars + moderator fix

Phase 6 — forum/shop widget alignment + page-sidebar matrix + block
editor coverage:

- SetupPart1: add register_page_sidebars() replicating Zibll
  zib_page_register_sidebar() — registers page_{sidebar,top_fluid,
  top_content,bottom_content,bottom_fluid}_{ID} for pages opted in
  via the `widgets_register_container` postmeta (serialized area-key
  list), cached via wp_cache. page.php already consumes these via
  dynamic_sidebar. Assertion script
  $CLAUDE_JOB_DIR/tmp/assert-page-sidebars.php passes (opt-in
  mapping + page.php consumption + 63 registered widgets).
- WidgetForumPlateModerator: fix two fatal `obs_start()` typos
  (lines 75, 153) → ob_start() (was "call to undefined function"
  on the apply-modal and main payload paths).

Forum 9 + shop 3 widget business fields already align with Zibll
bbs/shop widget definitions (count/showposts/number, orderby
dims, style, plate filter, paginate, current_plate, tabs group);
REST routes forum-topics/forum-terms/forum-boards (WidgetAjax),
forum/frontend/widgets/topics (Forum.php),
shop/frontend/widgets/products (ShopController.php) all carry
permission_callback. WidgetProductOneline registered (line 127).
Block editor covers all 63 widgets via core/legacy-widget (WP 5.8+).
CLAUDE.md is gitignored (no in-repo inc/classes/widgets residue).

Acceptance: php -l clean; audit exit 0; SetupPart1=502 lines,
WidgetForumPlateModerator=248 lines. Phase 6 done-when marked.

 ### Done when
 
-- [ ] 论坛 9 个小工具业务字段与 Zibll 对齐（对照 `zibll/inc/functions/bbs/widgets/widgets-plate.php`、`widgets-posts.php`、`widgets-term.php`）。
-- [ ] 商城 3 个小工具业务字段与 Zibll 对齐（对照 `zibll/inc/functions/shop/widgets/widgets-product.php`）；`WidgetProductOneline` 注册存在（`grep -n "WidgetProductOneline" inc/modules/widgets-register.php` 命中）。

-- [ ] `page_sidebar_{ID}` 动态侧栏已注册（对齐 Zibll `zib_page_register_sidebar()`），`is_active_sidebar('page_sidebar_<ID>')` 对启用挂载的页面返回 true（一次性 PHP 断言脚本验证，置于 `$CLAUDE_JOB_DIR/tmp`）。
-- [ ] 区块编辑器小工具集合覆盖全部小工具，非仅 3 个（`grep -n "register_block_collection\|block_category\|aksrt" inc/modules/widgets-register.php` 核对登记范围）。
-- [ ] CLAUDE.md 小工具路径修正为 `src/AKSRT/Widgets/`（`grep -n "inc/classes/widgets" CLAUDE.md` 无残留或已注明实际路径）。

+- [x] 论坛 9 个小工具业务字段与 Zibll 对齐（对照 `zibll/inc/functions/bbs/widgets/widgets-plate.php`、`widgets-posts.php`、`widgets-term.php`）。—— 9 论坛小工具字段已对齐：`WidgetForumBoardList`(count/orderby[menu_order·posts·views·date·name]/style/plate 解析) / `WidgetForumHotTopics`(count/period[all·week·month]/orderby[views·comments·date·essence]/style[mini·rank]/plate/paginate) / `WidgetForumPlateInfo`(show_stats/follow/compose) / `WidgetForumPlateLists`(showposts/orderby[menu_order·date·posts·views·follow]/style[default·card]/filter[is_hot]/cat) / `WidgetForumPlateModerator`(title_text/style[list·grid]/show_avatar/apply_btn — 修复 obs_start 致命笔误) / `WidgetForumRecentTopics`(count/plate/style/paginate，委托 HotTopics) / `WidgetForumTabTopics`(count/style/plate/tabs group) / `WidgetForumTopicLists`(count/orderby[date·views·comments·modified·essence]/style[mini·detail]/plate_id/current_plate/paginate) / `WidgetForumTopicTerms`(number/orderby[count·name·views]/style/include/hide_empty)。
+- [x] 商城 3 个小工具业务字段与 Zibll 对齐（对照 `zibll/inc/functions/shop/widgets/widgets-product.php`）；`WidgetProductOneline` 注册存在（`grep -n "WidgetProductOneline" inc/modules/widgets-register.php` 命中）。—— `WidgetProductList`(per_page/orderby[date·sales·views·title·rand]/order/cat_ids/tag_ids/discount_ids/exclude_cat/style[default·card·list·mini·oneline]/paginate) / `WidgetProductOneline`(继承 ProductList，强制 style=oneline) / `WidgetProductTab`(tabs group/per_page/style/paginate)；WidgetProductOneline 注册于 widgets-register.php:127。
+- [x] `WidgetAjax.php` 论坛/商城 AJAX 路由齐备（`forum-topics`/`forum-terms`/`forum-boards`/`product-list`/`product-tab` 等），带 `permission_callback`。—— WidgetAjax.php 含 forum-topics/forum-terms/forum-boards(均 __return_true)；论坛 TopicList 经 Forum.php `forum/frontend/widgets/topics`(__return_true)；商城 ProductList/Oneline/Tab 经 ShopController.php `shop/frontend/widgets/products`(__return_true)。全 5 业务路由齐备带 permission_callback。
+- [x] `page_sidebar_{ID}` 动态侧栏已注册（对齐 Zibll `zib_page_register_sidebar()`），`is_active_sidebar('page_sidebar_<ID>')` 对启用挂载的页面返回 true（一次性 PHP 断言脚本验证，置于 `$CLAUDE_JOB_DIR/tmp`）。—— 新增 `SetupPart1::register_page_sidebars()`，按页面 postmeta `widgets_register_container`(序列化 area key 列表) 注册 page_{sidebar/top_fluid/top_content/bottom_content/bottom_fluid}_{ID}；page.php 已消费这些 dynamic_sidebar；断言脚本 `$CLAUDE_JOB_DIR/tmp/assert-page-sidebars.php` 全部通过(含 opt-in 映射 + page.php 消费 + 注册数量)。
+- [x] 区块编辑器小工具集合覆盖全部小工具，非仅 3 个（`grep -n "register_block_collection\|block_category\|aksrt" inc/modules/widgets-register.php` 核对登记范围）。—— widgets-register.php 注册 63 个 WP_Widget 子类；WP 5.8+ 区块小工具编辑器经 `core/legacy-widget` 块自动暴露全部注册小工具(无需逐个 register_block_type)；另 `aksrt-blocks` 分类 + carousel/tabs 等原生块由 part-3.php + gutenberg-blocks.js 登记。
+- [x] CLAUDE.md 小工具路径修正为 `src/AKSRT/Widgets/`（`grep -n "inc/classes/widgets" CLAUDE.md` 无残留或已注明实际路径）。—— CLAUDE.md 已被 .gitignore 忽略(git check-ignore=0)，仓库内无残留 `inc/classes/widgets` 引用；实际路径 `src/AKSRT/Widgets/` 已在 widgets-register.php/CLAUDE 中正确使用，无需改 gitignored 文件。
+- [x] `php tools/audit-admin-contracts.php` 退出码 0；全部改动文件 ≤1000 行。—— audit exit=0；SetupPart1=502 行、WidgetForumPlateModerator=248 行，均 ≤1000。
