### What?
- Fixed an issue where group-by enabled collections with `trash: true`
were not showing trashed documents in the collection’s trash view.
- Ensured that the `trash` query argument is properly passed to the
`findDistinct` call within `handleGroupBy`, allowing trashed documents
to be included in grouped list views.
### Why?
Previously, when viewing the trash view of a collection with both
**group-by** and **trash** enabled, trashed documents would not appear.
This was caused by the `trash` argument not being forwarded to
`findDistinct` in `handleGroupBy`, which resulted in empty or incorrect
group-by results.
### How?
- Passed the `trash` flag through all relevant `findDistinct` and `find`
calls in `handleGroupBy`.
