Refactor: Enhance server join flow and navigation

- Modified `DiscoverServersList` to accept an `onJoinToServerSuccess` callback, which is invoked with the server ID upon successful joining.
- Updated `ServerInviteHandler` to pass the server ID to the `onJoinSuccess` callback.
- Integrated the `onJoinToServerSuccess` callback in `ChannelSideDrawer` to navigate to the joined server after a successful join from the discover servers list.
