This change adds full organization and entity support to the BetterAuth + Autumn integration by switching to a SQLite store, introducing new middleware and plugin options for organization context, and exposing CRUD endpoints and React hooks (useEntity, identifyOrg, etc.) in the Next.js frontend. It greatly expands authentication and billing capabilities—letting users create/join organizations, set active orgs, and manage “entities”—and updates a wide range of UI components for consistency. However, the PR is very large and lacks documentation or tests, commits database files and hard-coded URLs, and could introduce breaking changes or security/maintenance risks.
