ModuleSettings audit fields not updated on setting change

## Describe the bug
The audit fields (`LastModifiedByUserID` & `LastModifiedOnDate`) in the `ModuleSettings` table are not updated when changing Reports settings.

## To Reproduce
Steps to reproduce the behavior:
1. Create a Reports module instance.
2. Change the `Query` setting.
3. `ModulesSettings` row, `dnn_ReportsDS_DotNetNuke_Query`, is updated, but not the audit fields.

## Expected behavior
The `LastModifiedByUserID` & `LastModifiedOnDate` ModuleSettings columns are updated when changing a row in that table.

## Additional context
This is important for tracking who changed settings on Reports modules.
