Add Club.archived_at with active()/archived() managers, archive() and restore(). An archived club stops resolving in ClubTenantMiddleware, so its subdomain behaves as unknown — archiving is a real deactivation, not a cosmetic flag — while every row it owns is retained. There is no hard-delete path, deliberately. A club with any data cannot be deleted anyway (ClubMembership PROTECTs its Season, and the shop chain PROTECTs more), and invoices generally must be kept.
