fix(helpdesk): neutral count badges, bordered tables, critical legend

- Count badge in section title is always neutral (no warning color)
- Critical highlighting only on ticket number, not entire row
- Ticket tables have border + border-radius + subtle header background
  matching the existing table widget pattern
- Legend at bottom explains the warning color when critical tickets exist
