feat(admin): rebuild ban page to mirror the reference theme

- rename the users.php submenu to 举报&禁封申诉 and the page heading to
  用户禁封申诉及用户举报管理
- merge report tickets and ban appeals into one Zibll-style queue:
  type filter buttons (全部/禁封申诉/用户举报), status subsubsub
  (全部/待处理/已批准/已拒绝), search box, sortable widefat table with
  the same column set (状态/类型/提交用户/详情/提交时间/更新时间),
  inline process forms and 20-per-page pagination
- report process form shows the reported target, restriction status and
  an enforcement action select; appeal form offers approve/reject radios
  with a message to the user
- move restriction enforcement into ReportCenter::apply_action so REST
  and the native page share one implementation; add get_report_row()
- drop the old three-tab rendering (reports/appeals tabs) and fix all
  notice/mail/SPA links to the merged page
