All literal "team" tier-value references renamed to "family" across API routes, admin UI, OpenAPI schemas, and lib/tiers.ts. The DB enum value itself is renamed in place via ALTER TYPE ... RENAME VALUE (migration 0044) rather than drizzle-kit's auto-generated drop-and-recreate-the-enum migration, which would have failed against any existing row still holding 'team' — RENAME VALUE preserves existing data with no cast/backfill needed. Also adds STRIPE_PLAN.md — a full Stripe billing integration plan (Checkout+Portal, tier→Price mapping, admin billing dashboard, and a multi-user Family-group design since Family is meant to cover several accounts under one subscription, not one payer). Planning only, no Stripe code yet. v0.47.0
