feat: Add comprehensive API integration tests with authentication, RBAC, and endpoint coverage for all platform handlers

- Add TestSetup struct with DB/Router/AuthService/test users/JWT tokens for test environment initialization - Add setupTest function with SQLite in-memory database, user/plugin/automation/config/auth session migrations, and test user creation with admin/operator/viewer/user roles - Add makeRequest helper for authenticated HTTP requests with Bearer token and JSON body support
