[Refactor] Simplify actions dispatching in front-end code

Description

Updating a variable ('Update') or triggering a callback ('ActionName') requires the React component to create two hooks (Dispatch and Module), them create the Action object (create*Action) then dispatch. These two basic front-end operation are so common that it would be wise to simplify their API, at least for extension library coders.

A proposal would be to create a 'Actions' hooks that would return a 'sendAction' and a 'sendUpdate' pair of functions that would encapsulate most of the legacy API complexity. These would rely on the legacy API that would not be modified.
