UI for Notifications

As part of the preparation for version 1.1.0, we introduced a Toast-like (Bootstrap) notification system for maxDEV.

maxDEV is a Kotlin Multiplatform application and uses the Jetpack Compose declarative UI framework. Currently, it is integrated only for the Redis Client dev tool. However, the new notifications system has been implemented as a reusable UI component; all other tools can benefit from it.
