Remove WindowManager, separate functionality into smaller modules (#2682)

* Move sendToRenderer to respective singletons

* Move to using ViewManager call for getting view by webContentsId

* Move show and create logic to main window, handle deep linking seperately

* Move resizing logic and event handing to mainWindow

* Move server switching logic to main/app

* Move tab switching logic to main/app, rely on showById for most usage

* Migrate remaining functions, remove windowManager objects, set up imports for self-contained singletons

* Fix E2E tests

* Update src/main/app/servers.ts
