字段全量比对收口：对齐 Zibll 默认值并后移等级/徽章入口

继续 Workstream C 全量字段比对，并按用户裁定处理冲突：
- UsersLevel / UsersBadge 采用“保留但后移”策略，不兼容旧数据接口，继续沿用当前新型
  sections/router 体系，在 users 主线中降权后移到 compat tools 分区。
- 按 Zibll 实际 options 默认值收敛一批高影响字段，打通 PHP schema + 前端 schema 两层：
  * global/search: search_posts / search_no_page / search_custom_key_s / search_cat -> true
  * forum: bbs_show_new_plate / bbs_post_pay_hide_type_s / bbs_post_pay_vip_price_s /
    bbs_reply_paginate_ias_s / bbs_comment_upload_img / bbs_rewrite_suffix_html_s -> true
  * shop: shop_s -> true, shop_breadcrumbs_shop_home -> false,
    shop_rewrite_suffix_html_s -> true
  * users: user_signup_no_repas / message_auto_clear_s / post_rewards_s /
    user_report_img_s -> true
  * post-list: cat_s -> false

验证：
- php -l 检查所有改动过的 PHP schema 文件均通过
- node --check 检查所有改动过的前端 schema 文件均通过
- shim 校验确认 users-level/users-badge 已从 users 主分区移出并以 secondaryEntry=true
  落入 compat tools，且全站无路由碰撞
- 注：本 worktree 下缺少可执行 vite，未能在隔离副本中复跑 npm build；此前主副本同批次
  IA 修正构建通过，本次继续只改 schema/sections 常量与默认值，已用语法校验覆盖
