Refactor Windows menu and tray icon management

Removed global registries and simplified Menu/MenuItem creation logic. Updated tray icon implementation to use std::optional for title and tooltip, improved visibility checks, and removed unused fields. Refactored TrayManager to eliminate hidden window management and related Windows-specific code, focusing on core tray icon tracking.
