feat(club): archive clubs instead of deleting them

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.
