SliverSpacing class
A sliver widget that creates vertical spacing at the end of a chat list.
This widget is primarily used to account for the height of the composer, optional bottom padding, and the keyboard (when visible). It consumes ComposerHeightNotifier to dynamically adjust its spacing based on the composer's height and uses KeyboardMixin to react to keyboard visibility changes.
