Add missing org API routes and fix registration gate

- Create /api/org (GET details, PUT update)
- Create /api/org/members (GET list)
- Create /api/org/invitations (GET list, POST create)
- Create /api/org/locations (GET list with collection days, POST create)
- Fix registration: check org count instead of user count so
  a fresh domain setup works even if orphaned users exist
  from a prior AUTH_SECRET rotation
