"""profiles.configure honours the model selection guard (#95293 remainder).

The Bots-mode editor writes a profile's default model through
``profiles.configure`` — a surface that historically bypassed the
data-policy / expensive-model selection guard every other model-switch path
enforces (``config.set model`` answers ``confirm_required`` and waits for a
``confirm_expensive_model`` resend).  A guarded pick made from the Bots
surface was therefore applied silently, with no confirm flow anywhere.

These tests pin the same handshake contract on ``profiles.configure``:

* a guarded model WITHOUT ``confirm_expensive_model`` answers
  ``confirm_required`` + ``confirm_message`` and writes NOTHING;
* the confirmed resend (``confirm_expensive_model: true``) writes;
* unguarded models keep writing exactly as before.
