fix: non streamoutput sometimes (#7512)

* feat(migrate): add default settings for assistants during migration

- Introduced a new migration step to assign default settings for assistants that lack configuration.
- Default settings include temperature, context count, and other parameters to ensure consistent behavior across the application.

* chore(store): increment version number to 115 for persisted reducer
