[PM-1504] Migrate Dialogs to DialogService (#5013)

This PR introduces a generic `DialogService` which can be used by all the clients. This allows us to decouple dialogs from the `PlatformUtilsHelper`.

The `DialogService` provides a new method, `openSimpleDialog` which is the new interface for that type of dialogs.

This gives us 3 different implementations: 
- Web: DialogService modern dialogs
- Browser: SweetAlert
- Desktop: Native electron based
