feat: queues have default team, tickets inherit it

- team_id on queues table (optional, can be overridden per-ticket)
- Ticket creation auto-sets team_id from the queue's default
- Queue admin form has team selector (scrip flow node 03)
- Queue API (POST/PATCH) accepts team_id

No enforcement — just a helpful default. Teams and queues
are loosely coupled, not hierarchically locked.
