* fix(presets): scope expand-prompt model resolution to owner
/api/presets/expand resolved its model endpoint with no owner, so in a
multi-user setup it could match another user's endpoint and use its URL
and decrypted api_key. Pass effective_user(request) to _resolve_model so
resolution is owner-scoped. Adds a regression test.
* fix(presets): scope teacher and audit model resolution to owner
