refactor: reduce webview lock contention (#6271)

* refactor: replace handle::Handle::get_window() with WindowManager::get_main_window() in multiple files

* refactor: enhance WindowManager to return window state alongside the main window instance

* refactor: update useProfiles and ProfilePage to support profile overrides and improve patchProfilesConfig return type

* refactor: enhance handle_success to check main window existence before notifying profile changes

* refactor: simplify get_main_window_with_state by using pattern matching and improve window state handling

* refactor: fix window activation by removing unnecessary reference in activate_existing_main_window

* refactor: remove redundant macOS conditional for window_manager import
