feat: Implement multi-tenancy, multi-user, and quota management
This commit introduces a comprehensive set of features for multi-tenancy, multi-user management, and resource quota enforcement.
Key changes include:
- **Quota System Definition:**
- Added a `tenant_quotas` table and corresponding `TenantQuota` model to store quota limits for each tenant.
- Defined a preliminary structure for quota plans (e.g., Free, Basic, Premium) although the plan definitions themselves are expected to be managed by an external billing system.
- **Billing System Integration (Mocked):**
- Extended `BillingService` with a `get_tenant_quota` method to fetch quota information (currently mocked).
- The `Tenant` model now has a `quota` property to access this information.
- **Quota Enforcement:**
- Introduced a `QuotaService` to manage quota checks and handle overages.
- Integrated quota checks into the creation/upload processes for:
- Users (`TenantService.create_tenant_member`)
- Documents (`DatasetService.save_document_with_dataset_id`, `DocumentService.check_documents_upload_quota`)
- Apps (`AppService.create_app`)
- Datasets (`DatasetService.create_empty_dataset`)
- Added a `QuotaExceededError` custom exception.
- **Multi-User Management Enhancements:**
- Reviewed and confirmed that existing Role-Based Access Control (RBAC) is compatible with the new quota features.
- Ensured that quota-related actions (like viewing usage) are restricted by user roles (owner/admin).
- **API Endpoint Updates:**
- Created a new API endpoint `/billing/quota/usage` for tenant owners/admins to view their current resource usage against their quotas.
- Existing resource creation API endpoints now implicitly enforce quotas through service-level checks.
- **User Interface Updates:**
- Modified the billing page (`web/app/components/billing/plan/index.tsx`) to use a new `UsageInfoContainer` component.
- The `UsageInfoContainer` (`web/app/components/billing/usage-info/index.tsx`) fetches and displays detailed quota usage (limits and current consumption) for various resources from the new API endpoint.
- Updated relevant TypeScript types for UI components.
- **Testing:**
- Added unit tests for `QuotaService` covering various scenarios like quota checking, overage handling, and usage summary generation.
- Added integration tests for the `/billing/quota/usage` API endpoint, verifying success cases, authentication, and authorization.
- **Documentation:**
- Prepared a comprehensive summary of changes required for the User Guide, API Documentation, and Developer Documentation to reflect the new features.
These changes provide a solid foundation for managing tenants, users, and resource quotas within the application, enhancing its capabilities for different subscription tiers and usage levels.
