fix(app): fix SQL query w/ enum for python 3.11 (#6557)

## Summary

Python 3.11 has a wonderfully devious breaking change where _sometimes_
using enum classes that inherit from `str` or `int` do not work the same
way as they do in 3.10 when used within string formatting/interpolation.

This breaks the new gallery sort queries. The fix is to use
`order_dir.value` instead of `order_dir` in the query.

This was not an issue during development because the feature was
developed w/ python 3.10.
