fix(report): unify the frontend report entry and modal

- enqueue report.js on singular pages too: the single meta box and
  comment report buttons rendered without their script handler, so
  clicking the report item did nothing
- align the report runtime default with the admin schema and the
  reference theme (user_report_s default true) so the public user
  home cover menu shows the report entry
- rebuild report.js on top of AksrtModalRuntime following the
  reference theme modal format: red warning header, preset reason
  badges with an other-reason textarea, violation link field, detail
  description and a cancel/submit footer; submit goes through the
  unified /report/submit endpoint
- keep report inside the comment three-dot dropdown and enrich the
  payload (target name/avatar) for the modal; inject configured
  report categories via aksrtData.reportCategories
- update the report contract test accordingly
