Add an explicit registry with capability hooks for migrations, routes,
workflows, config, and UI assets. Move FedWiki fully and Stripe's
separable
store, workflow, and webhook pieces under internal/integrations.
Drive startup wiring from declarations, including config validation,
secret
file pairs, CSRF exemptions, UI composition, and workflow startup. Move
integration DB roles and grants into their owning migration streams, and
route outbox writes through a shared enqueue helper.
