Kanban board β new "in flight" design.
Same data + same drag-drop semantics as before; the difference is purely
visual: bigger editorial header, stats card, prettier cards with chips
+ first-name pills + π€ AI badge, drop-target shadow, etc.
We still hit the same APIs:
- /team-inbox/api/bootstrap β members, teams, ai_agents
- /team-inbox/api/queue?status=all&tab=all&per_page=200
- /team-inbox/api/conversations/{id}/{resolve|reopen|snooze|priority|assign|unassign|assign-agent}

{{-- ========== PAGE HEADER ========== --}}
{{-- Device filter β hidden when the workspace has 0β1 devices.
JS toggles visibility and populates options after bootstrap
via renderDeviceFilter(). --}}
