%%% @doc Roster management (Mnesia storage).
%%%
%%% Includes support for XEP-0237: Roster Versioning.
%%% The roster versioning follows an all-or-nothing strategy:
%%% - If the version supplied by the client is the latest, return an empty response.
%%% - If not, return the entire new roster (with updated version string).
%%% Roster version is a hash digest of the entire roster.
%%% No additional data is stored in DB.
