//! Request handlers for the admin UI
//!
//! This module has been refactored into sub-modules for better organization:
//! - assets: Static asset serving
//! - admin: Admin dashboard and server management
//! - workspace: Workspace management operations
//! - plugin: Plugin management operations
//! - sync: Synchronization operations
//! - import: Data import operations
//! - fixtures: Fixture management operations
