feat(db): manually set timestamps for SQLite compatibility

Add explicit datetime.utcnow() assignments for created_at and updated_at fields in LLMModelConfigsRepository to ensure proper timestamp handling with SQLite. This addresses issues where SQLite may not automatically populate these timestamp fields during create and update operations. Changes applied to both user and group configuration methods for consistency.
