[bug]: JQMIGRATE setting does nothing

### FreePBX Version

FreePBX 17

### Issue Description

There is an advanced setting to disable the use of jquery-migrate. Its value is never checked. This would be a simple change to BMO/Views.php to conditionally add the file to the list of scripts.

### Operating Environment

FW 17.0.34

### Relevant log output

```shell

```
