Shared account center foundation

One shared account for PayMyShop and FlowMyShop.

HelpMyShop is now set up to become the shared account portal layer. The portal uses the same Supabase identity, the same tenant record, and the same product entitlement data that already exists behind the product apps.

Same login identitySame shop tenantSeparate product entitlementsSeparate operational apps

What this portal owns

Shared identity, shop account, product subscriptions, billing overview, and future Stripe customer management.

What stays separate

PayMyShop and FlowMyShop remain their own product apps with their own operational routes, UI, and product-specific workflows.

First implemented step

Read-only shared account views are now available at /account for both tenant users and root users, without changing existing product logins.
