refactor: sorting by volume change in a specific period

[crnkovic]

Summary

https://app.clickup.com/t/86dr7u6x3

Built from #576 as we use the columns from that PR

Keep in mind that the table will still show the volume column and not the volume in the specific period (avg_volume_7d, etc), so it may appear that sorting is not working as volume columns won't be alright, but that's a part of another task. But you can open the database GUI, manually order by any of those values and check that it properly sorts.

As a part of this PR, I added orderByWithNulls scope to the Collection model. We've been repeating the same logic of ordering NULL values first in ASC order, and last in DESC order, so I created a scope for allow some code reuse.
