feat: full parity pass - suspend enforcement, report modal polish, wechat notify

- Restriction: add is_suspended/get_active_suspend; comment block now covers
  suspend (小黑屋) in addition to mute, with reason in the deny message
- FrontSubmitSave::persist: block post/draft/edit submission for suspended
  users (reference-theme semantics: 小黑屋 loses all publishing rights)
- report.js: close icon switched from fa-times to the SVG sprite ic-close
  (#icon-close), same as reference theme; textareas gain autoHeight growth
  (hidden 'other reason' box skips the first measurement)
- WeChatNotify: NOTIFY_TYPES now includes report/system so report results
  and account restriction notices fan out to WeChat template messages;
  generic title/description fallback for template values
- contract tests: +3 tests (suspend enforcement, modal polish, wechat types)
