The subscription machinery leaves the code — Kanban/Tier excised, StoreKit wiring unwound

The 2026-08-08 one-version ruling (12-editions.md ▸ PIVOT 2026-08-08) carried out: Kanban/Tier/
deleted wholesale (Tier, ProEntitlement, ProProducts, ProStorefront, the never-rendered
ProSettingsSection) with TierTests and Configuration.storekit, whose project.yml resource entry
and scheme storeKitConfiguration go with it. AppModel loses the entitlement, the currentTier
seam, BoardSession.tier, and the purchase flow's reopenOpenBoards (its only caller was the
storefront); AppDelegate's launch keeps only the appearance application. The three tests
pinning the recorded tier and the reopen are deleted with their subject. The network-client
entitlement stays — the sync capability to come needs it regardless — and the HistoryProviding
seam stands untouched. 2,686 unit tests green (2,707 minus the 21 that tested what left).
