feat: Add subscription management system

- Add subscription fields to organizations (status, plan, trial_ends_at, etc.) - Add subscription middleware for access control - Add /auth/me returns subscription info - Add admin endpoints for subscription management: - GET/PUT /admin/organizations/:id/subscription - POST /admin/organizations/:id/pause - POST /admin/organizations/:id/activate - POST /admin/organizations/:id/extend-trial - GET /admin/subscriptions (with filters) - New orgs get 14-day trial automatically
