Backend:
- team_id column on tickets table
- team_id filter in GET /tickets (resolves team members)
- team_id in UpdateTicketSchema + PATCH handler
- SetTeam transaction type

Frontend:
- Team selector in ticket detail properties sidebar
- My team's tickets in sidebar (when user belongs to a team)
- team_id passed through to API from ticket list page
