A new chat with the sandbox switched off in the composer showed no
"switched off" notice. GET /api/chats/draft/addons took only the model
and the agent, so it always reported the default commands state.
Accept the draft's switches as comma-separated query parameters
(addons_off, builtins_off, builtins_on), check them as the create request
does, and apply them to the draft record before the commands state is
worked out. The composer sends its choices each time an add-on or a
built-in group is switched, so the notice follows the switch.
