Fix Report model field name

[olliestanley]

Close #3051. This turned out to be an easy fix. If the frontend currently reads the parameter as type it will need to be adjusted to report_type (cc @AbdBarho, just let me know where to look if you want me to add that change to this PR also)

I also made a formatting change as pre-commit on commit was conflicting with pre-commit run --all-files (how?)
