feat(teams): add teams app with roster and staff assignments

Introduce the teams app: Team and Position (both club-scoped, with
per-club unique names), TeamMembership (season-scoped roster with jersey
number + captain flags, unique member and jersey per team/season), and
StaffAssignment (coaching/staff, filtered to staff positions). All
uniqueness expressed as UniqueConstraints.

Register every model in the admin (with roster + staff inlines on Team)
and cover the models with tests. Fix two model bugs surfaced by the
system check: StaffAssignment.position reused TeamMembership's reverse
accessor (Position.team_memberships) and duplicated its constraint name.
