Queue detection: any member with 'warteschlange' in support_user name
(or empty) is treated as queue, not as a regular agent.
Current tab: queue cards shown at top with a wait time summary
(Ø/Min/Max from open ticket ages). Agents listed below.
Historical tab: queue cards shown before agents, same performance
widget pattern.
No backend changes — purely client-side separation using existing data.
