fix(ui): fold the "No reasoning" chip into the effort picker
The chat composer had two controls for one idea: the effort picker
with a "None" level, and a separate "No reasoning" chip. The chip
also hid reasoning traces that a model sends despite
reasoning_effort "none", which "None" did not. The chip disabled the
picker while it was on.
Choosing "None" now hides those traces and stays selectable, so the
chip, its toasts and the /reasoning slash action are removed. A chat
saved with the old reasoningOff flag loads with effort "none", so it
keeps hiding reasoning.

The chat could not set reasoning_effort or turn reasoning traces off.
Add an effort menu and a "No reasoning" toggle to the composer chips,
and the matching /effort and /reasoning slash actions. Both are stored
per chat. The effort menu defaults to the model default, which sends no
reasoning_effort, so existing chats behave as before.
Chosen effort goes out as the per-request reasoning_effort field. The
toggle sends "none", which the server maps to enable_thinking=false, and
also drops any reasoning the model still returns, so the thread shows
only the answer.
