Subject: [PATCH] Add mistral/mistral-small-2603 model settings

Closes #5000.

Reporter got 'The LLM did not conform to the edit format' - aider had
no model-settings entry for mistral/mistral-small-2603 so it fell
through to default edit_format: whole, which the model didn't reliably
return.

Adds a single entry following the pattern of other coder-class models
in the file: edit_format: diff, weak_model_name pointing at
mistral/mistral-small-latest, use_repo_map enabled, reminder: sys.
